5 + 5 + 5 = 15

4 + 4 + 4 = 12

1) 4/5 = 12/15

3in : 4ft = xin : 24ft

4 * 6 = 24

3 * 6 = 18

Evaluate A 2-B 2 for A = 3 and B = -4

r-ruslan [8.4K]

Hello there, and thank you for posting your question here on brainly.

Since we know what both of the exponents are, we can rewrite the equation for it.

3 * 2 - (-4)

We can evaluate from here.

I can see we have a positive number subtracting a negative number.

Use the rule where x - (-y) = x + y

2 * 3 + 4

Now we can get solving.

2 * 3 ==> 6

6 + 4 ==> 10

10 is the final answer.

Hope this helps! ☺♥

The diagonals of rectangle ABCD intersect at point E. If AE = 2x + 5, and BD = 5x + 2, what is AC?

Mkey [24]

C. 42 units

Step-by-step explanation:

I have attached a diagram to help you understand this problem. By looking at the diagram you can see that AE is half of BD, and that BD will be equal to AC. So we need to figure out the length of line BD to get AC.

To do this, you will multiply the length of AE by 2 and set it equal to BD.

$2(2x+5)=5x+2$
