9514 1404 393

Answer:

  11

Step-by-step explanation:

X'Y' = 2XY . . . . lengths are related by the dilation factor

22 = 2XY . . . substitute the given value

11 = XY . . . . . divide by 2

What’s the answer to this question
Andreas93 [3]

Answer:

ab

Step-by-step explanation:

When all of the variables are the same in a problem, think of them as the same term. They can be added and subtracted just as you would add and subtract normal numbers.

For example if I have 5 bananas on a table and take away 3 bananas. I only have two bananas left (2b). It's the same when there are variables!

Subtract 9 from 3:

-6ab+7ab

Add -6 to 7:

ab

Your final answer is ab!

The perimeter of a triangle is 29. One side of a triangle is 5 less than twice the side of the shortest length. The third side i
PolarNik [594]

Answer:

  • 7, 9, 13

Step-by-step explanation:

Let the sides of the triangle be a, b and c.

<u>We have:</u>

  • P = a + b + c = 29
  • a = 2b - 5
  • c = b + 6

<u>Substitute values and solve for b:</u>

  • 2b - 5 + b + b + 6 = 29
  • 4b + 1 = 29
  • 4b = 28
  • b = 7

<u>Find a and c:</u>

  • a = 2*7 - 5 = 14 - 5 = 9
  • c = 7 + 6 = 13

<u>The sides are:</u> 7, 9, 13

Which of the following options is an equivalent function to f(x) = 2(5)^2x? choices: f(x) = 50^x f(x) = 100^x f(x) = 2(25)^x f(x
Stells [14]

For this case we have the following function:

f (x) = 2 (5) ^ {2x}

By power properties we can rewrite the function as follows:

f (x) = 2 ((5) ^ 2) ^ x

We have then:

(5) ^ 2 = 25

Then rewriting the function we have:

f (x) = 2 (25) ^ x

Answer:

an equivalent function to f (x) = 2 (5) ^ {2x} is:

f (x) = 2 (25) ^ x

What are the zeros of the polynomial function f(x) = x(x + 5)(x – 8)?
elena-14-01-66 [18.8K]

0,-5,8

To find the zeros, set each equation equal to 0

x=0

x+5=0

x-8=0

Then solve

x=0

x=-5

x=8

So the zeros are 0,-5, and 8
