Answer:

1*3 = 1+7(3) = 22

5*22 = 5+ 7(22) = 159

159 is your answer.

hope this helps!

The value of expression 5 × ( 1 × 3 ) is, 159.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

⇒ m × n means (m + 7n).

Now, We can find the value of 5 × ( 1 × 3 ) as,

⇒ 5 × ( 1 × 3 )

⇒ 5 × (1 + 7×3)

⇒ 5 × (1 + 21)

⇒ 5 × 22

⇒ 5 + 7 × 22

⇒ 5 + 154

⇒ 159

Answer:

(x+3)(x+4)

Step-by-step explanation:

Given:

→x² + 3x + 4x + 12​

Take common from x² + 3x and 4x + 12​

Now,

[tex]\hookrightarrow x(x+3)+4(x+3)\\[/tex]

Here,

(x+3) can be written as one.

Then,

[tex]\hookrightarrow (x+3)(x+4)\\[/tex]

And it is our answer.

Answer:

[tex]\displaystyle [x + 3][x + 4][/tex]

Explanation:

Find two quantities that when summed to 7, they also multiply to 12. Those will be 4 and 3. Sinse the entire expression is positive, the quantities STAY positive. Moreover, there is not much wourk to be done here BECAUSE the leading coefficient is one. This is all you can do:

[tex]\displaystyle x^2 + 7x + 12 \\ \\ \boxed{[x + 3][x + 4]}[/tex]

Answer:

above is the solution to the question

Given:

The stand sold 4 cherry snow cones for every 1 lemon snow cone sold.

There were 30 more cherry snow cones than lemon snow cones sold yesterday.

To find:

The number of snow cones which were sold altogether.

Solution:

Let x be the number of lemon snow cone sold.

The stand sold 4 cherry snow cones for every 1 lemon snow cone sold.

So, number of cherry snow cone sold = 4x

There were 30 more cherry snow cones than lemon snow cones sold yesterday.

[tex]4x-x=30[/tex]

[tex]3x=30[/tex]

Divide both sides by 3.

[tex]x=\dfrac{30}{3}[/tex]

[tex]x=10[/tex]

Total number of snow cones sold is

[tex]\text{Total number of snow cones sold }=x + 4x[/tex]

[tex]\text{Total number of snow cones sold }=5x[/tex]

[tex]\text{Total number of snow cones sold }=5(10)[/tex]

[tex]\text{Total number of snow cones sold }=50[/tex]

Therefore, 50 snow cones were sold altogether.

Step-by-step explanation:

n(n+1)=17+5(2n+1)

n^2 +n=17+10n+5

n^2 -9n-22

Splitting the middle term

n^2 -11n+2n -22

n(n-11)+2(n-11)

(n-11)(n+2)

As n cannot ne negative,

n=11 and 12(consecutive no.)

The two of the consecutive positive integers whose product is 17 more than 5 times their sum are 11 and 12.

An integer is a complete number, therefore, not including the decimals and fractions. And it that can be either positive, negative, or zero.

Integer examples include -5, 1, 5, 8, 97, and 3,043.

Non-integer numbers include: -1.43, 1 3/4, 3.14, and more.

Let the first of the two consecutive integers be represented by x. Then, the other number can be written as (x+1).

Now, the product and the sum of the two numbers can be written as,

Product = x(x+1) = x² + x

Sum = x + (x+1) = 2x + 1

Further, it is given that the product of two consecutive positive integers is 17 more than 5 times their sum. Therefore, we can write,

x² + x = 17 + 5(2x + 1)

x² + x = 17 + 10x + 5

x² + x - 17 - 10x - 5 = 0

x² - 9x - 22 = 0

x² - 11x + 2x - 22 = 0

x(x - 11) + 2(x - 11) = 0

(x - 11)(x + 2) = 0

x = -2, 11

Thus, there are two numbers that can fulfil the given condition but since it is mentioned that we only need two positive consecutive integers. Therefore, the two numbers are 11 and 12.

The answer is option B

Answer:

25.3 feet per second

Step-by-step explanation:

First, let's find how much did she go down in those 3 seconds.

266-190=76

Now, let's divide 76 by 3 to find how much did she go down in 1 second

76/3=25 R1

Now, let's change 25 R1 to a Fraction.

25 remainder 1 to fraction will be 25[tex]\frac{1}{3}[/tex]

Now, let's find the decimal answer

25[tex]\frac{1}{3}[/tex] will be 25.33(33333)

Now, let's round our answer to the nearest tenth

25.33

so, 3 is closest to 0 not to 10

So hence, our answer is 25.3

So, the submarines elevation was changing at a rate of 25.3 feet per second

Step-by-step explanation:

For Lauren's tower which he drew using only similar quadrilaterals the statement B is correct, which is the quadrilaterals are different shapes but the same size.

Quadrilateral is the plane shape which is closed polygon having which is made by using the four sides, four angles and four vertices.

The sum of all the interior angle in a quadrilateral is equal to 360 degrees.

The two quadrilateral are said to be a similar quadrilateral when the quadrilaterals are all the same size and shape.

Here, Lauren drew a tower using only similar quadrilaterals. Let's check all the statement about the quadrilaterals given as,

As for the similar quadrilaterals, quadrilaterals are all the same size and shape. Thus, the option B is the correct option.

Answer:

7 R 95

for this case, how many times does 99 go into 788? 0, because you must convert 78 to the tens place.

78 - 0 = 78

Drop the 8 from the zeros place.

How many times does 99 go into 788? 7(693)

788 - 693 = 95

▬▬In The End▬▬

The answer is 7, because that is the number on top, the result of the division is called the remainder.

A right angle = 90 degrees

A round angle = 360 degrees

1. 3 x 90 = 270 degrees

2. 4 x 90 = 360 degrees

Answer:

Step-by-step explanation:

The equation of the path of the book is an upside down parabola.

We can find the x-coordinate of the vertical axis.

The x-coordinate of the maximum point is

x = -b/2a

for a parabola written in the following form

f(x) = ax² + bx + c

We have -16t² + 24t + 30, so we have

a = -16

b = 24

c = 30

t = -b/2a = -24/(2 × (-16)) = -24/(-32) = 0.75

The maximum height occurs at time = 0.75 seconds.

Now we plug in the time into the equation to find the maximum height.

h(x) = -16t² + 24t + 30

h(0.75) = -16(0.75)² + 24(0.75) + 30

h(0.75) = -9 + 18 + 30

h(0.75) = 39

Using proportions, it is found that 700 students were surveyed in total.

A proportion is a fraction of a total amount.

In this problem, we have that 100 - 47 = 53% of the total number of students had blue as their favorite color, and this amount is of 371, hence:

0.53n = 371

n = 371/0.53

Done!

Answer:

Step-by-step explanation:

Note the x^2 term, 21 can be divided up into 1,3,7,21

and the constant term, 14 is divisible by 1,2,7

Also, note that -55 = -7*7 - 2*3

Break up 21x^2 into 7x*3x and -55x into -49x - 6x,

21x^2 - 55x + 14

= ((7x*3x) - 49x) - 6x + 14

= 7x*(3x - 7) - 2*(3x -7)

= (7x - 2)*(3x - 7)
