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)

This figure has two intersecting lines and a ray. What is the value of x?
37°
108°
72°
19°
Answer:
The value of x is D. 37°
Step-by-step explanation:
No need for math on this one, the angle next to x is 71° and is significantly bigger, so the only answer could be 37°.
The value of x will be 37°.
What is Vertically opposite angles?
Vertically Opposite Angles are the angles opposite each other when two lines cross.
Given that;
This figure has two intersecting lines and a ray.
Now, By the definition of vertically opposite angles, we get;
x° + 71° = 108°
Then, Solve for x as;
x° + 71° = 108°
Subtract 71 both side;
x° + 71° - 71° = 108° - 71°
x° = 37°
Thus, The value of x will be 37°.

The snack stand at the local baseball field sells cherry and lemon snow cones. Yesterday, the stand sold 4 cherry snow cones for every 1 lemon snow cone sold. If there were 30 more cherry snow cones than lemon snow cones sold yesterday, how many snow cones were sold altogether?
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.

Answer:
The no. are 11 and 12
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,

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

Enola gave out a survey to some students in her school about their favorite color. Students could choose between blue and purple. 371 of those surveyed said their favorite color was blue. 47% of the students surveyed said their favorite color was purple. How many students were surveyed in total?
Using proportions, it is found that 700 students were surveyed in total.
What is a proportion?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

Help Please Help Its A Math Problem : Maria threw her math book off a 30 foot building. The equation of the book can be represented by the equation: h(t)= -16t^2+24t+30 where t is the time in seconds and h is the height in feet. What is the maximum height of Maria's math book?
Question options:
0.75
30
39
12
p.s I will brainlist please and thank you.
Answer:
39 feet
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
