Corresponding sides have the same ratio, so
x/15 = 12/(12+8) = 3/5
x = 15*3/5
x = 9

Answer:
132, (D)
Step-by-step explanation:
area = base * height
= (5 + 6) * 12 = 11 * 12 = 132
A) 2000000000
5,909,999,222-3,999,002,135= 1,910,997,087 which is closest to answer A
Answer: E, A, D, C, B
Step-by-step explanation:
First, we need to get y alone. So we will add 7 to the side of the equation that has the 4y in it.
So the first one will be.
<em><u>Add 7 to both sides of the equation.</u></em>
Now the second one is
<em><u>4y = 25 + 7 </u></em>Because what you do to one side of the equation, you do to the other. So we add 7 to 25.
Then the 3rd one will be <u><em>4y = 32 </em></u>because 25+7 is equal to 32. But we still have that 4y on the other side of the equation. So the next equation is 4y = 32.
The second to last step is <em><u>Divide both sides by 4 </u></em>because thats
how you isolate y. So once you divide both sides by 4. You will get 8. Leading you into the next and final step.
<em><u>Y = 8</u></em>
And thats how you do it!
