Answer:

-4p^2-6p+1

Step-by-step explanation:

Answer:

The sum of two side lengths of a triangle must be greater than the length of the third.

So, if two side lengths are 3 and 7, the length of the third side must be less than 10 units.

However, it cannot be shorter than 4 units, as 3 + 4 = 7.

So your answer is: The third side of this triangle must not be shorter than 4 or longer than 10

Let me know if this helps!

Answer:

[tex] {2b}^{2} + 32b + 128[/tex]

Factor and get

[tex]x = - 8[/tex]

Answer + Explanation:

let x be the measure of angle x

let y be the measure of angle y

[tex]\left \{ {{x + y = 180} \atop {x=24+y}} \right.[/tex]

Now, solve:

plug x = 24 + y into x + y = 180

24 + y + y = 180

24 + 2y = 180

2y = 156

y = 78

Now, plug this back into the equation x = 24 + 78

x = 102

Answer:

x= 102

y= 78

Step-by-step explanation:

x+y=180

x= y + 24

2x-24 = 180

Answer: 99%?

Step-by-step explanation:

Answer:

238 miles

Step-by-step explanation:

340 miles = 5 hours

So get 1 hour by dividing by 5 on both sides

5/5 = 1 hr

340/5 = 68

So in 1 hour they travel 68 miles

You want to find 3 1/2 hours

Do 68 x 3 to get 3 hours

So it would be 68 x 3 =204

Plus the half an hour - which you get by doing 68/2 = 34

68 = 1 hour, so half of that must be half an hour

So to get the final distance you do 204 (3 hours) +34 (half an hour)

204 + 34 =238

Answer:

[tex]-\frac{17}{21}[/tex]

Step-by-step explanation:

Negative and positive is negative.

Negative and negative is positive.

Positive and positive is positive.

[tex]\frac{1}{3} +-\frac{7}{4}=\frac{1}{3}-\frac{7}{4} = -\frac{17}{12}[/tex]

Calculations:

Answer:

Fraction form: -1/2

Decimal form: -0.5

Step-by-step explanation:

1: Subtract 7 from both sides

7 - 6x = 9 - 2x

7 - 7 - 6x = 9 - 7 - 2x

6x = 2 - 2x

2: Add 2x on both sides

6x + 2x = 2 - 2x + 2x

-4x = 2

3: Divide both sides by -4 to get x by itself

-4x/-4 = 2/-4

x = -1/2

(Which can also be written as -0.5 in decimal form )

Answer:

14 sales

Step-by-step explanation:

1,200-250=950

70×14=970

We first need to subtract our normal pay out of the expectation.

1200-250=950 dollars

These 950 dollars have to be made from sales, and if each sale gives you 70 dollars, we just need to do simple division.

950/70=about 13.57

This meant that if we get 13 sales, we are not quite there at the goal yet, so we need to round up. Getting 14 as our answer.

Answer:

Yes by SAS

Step-by-step explanation:

if you do 42 / 18 you see that the relationship between the sides is 2.3333... so that is one proportional side

Then, you see that there is one angle in both triangles that is 76 degrees, so that is one equal angle

then, you can do 21 / 9 = 2.33333... which is the same as the first proportion which means that is another proportional side.

then you have a side, angle, and a side, so it's SAS

Answer:

9y - 27

Step-by-step explanation:

9(y - 3) = 9 * y - 9 * 3 = 9y - 27

Answer:

the answer would be 9y-27

Step-by-step explanation:

( 9 x y ) - ( 9 x 3 )

Answer:

Base = 3√5

Step-by-step explanation:

Given:

Hypotenuse = 9

Perpendicular = 6

Find:

Base(x)

Computation:

Using Pythagorean theorem

Base = √Hypotenuse² - Perpendicular²

Base = √9² - 6²

Base = √81 - 36

Base = √45

Base = 3√5

Answer:

.3

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'm not sure what the next now rule but I can give you the function.

y = 5 * 2^x

So the table is constructed by letting 0<=x<=8

For example if x is 3

y = 5 * 2^3

y = 5 * 8 = 40

When x = 3 does y come to 40? According to the chart it does.

Try another one

y = 5 * 2*6

y = 5 * 64

y = 320   Is that what the chart records? Yes it does.

If what the text now rule means is that from the current value of y, you can get the next value, then the formula would be

y_n = 2 * y_(n - 1)

y_7 = 2 * y_6

y_7 = 2 * 320

y_7 = 640

Answer:

Sandhya performed better.

Step-by-step explanation:

You can either or simplify the fractions:

[tex]\frac{630}{900}[/tex] and [tex]\frac{650}{1300}[/tex] to simpler forms like [tex]\frac{7}{10}[/tex] and [tex]\frac{1}{2}[/tex] from there you can make the [tex]\frac {1}{2}[/tex] and multiply it by [tex]\frac{5}{5}[/tex] to get [tex]\frac{5}{10}[/tex] and then from there you can see Sandya performed better.

OR

You can divide 630 by 900 and 650 by 1300

630/900 gives you 70

and

650/1300 gives you 50

Clearly, once again Sandhya performed better.
