Answer:
-54
Explanation:
First we need to use the distributive property on 7(x+5), so do 7×x + 7×5. Simplify that and you get 7x+35.
Subtract 35 from both sides and you get 7x= -63. Divide both sides by 7 and you get x= -9.
Now we can substitute -9 for x, so do 6×-9 and you get -54.
Hope this helps :)
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
