It actually doesn't matter how tall is Pedro's try last year. This year it is 2 feet less than his house, which doesn't grow.
17-2=15feet
First, subtract 12 and get it on the other side.
So you will get this:
-4/5(x+15)=-8
Next, you'll want to distribute the -4/5:
-4/5x-12=-8
Add 12
-4/5x=4
Multiply -4/5 (Usually you would divide here, but since it's a fraction, multiplying is simpler)
x=-3.2 (or -16/5)
Answer:
4x⁴y
Step-by-step explanation:
Square the -x
2x·2xy·(-x)²= 2x·2xy·x²
Use the commutative property of multiplication to rearrange the order
2x·2xy·x² = 2·2·x·x·x²·y
Use the associative property of multiplication to combine like terms
2·2·x·x·x²·y = ( 2·2)·(x·x·x²)·y
Simplify
( 2·2)·(x·x·x²)·y = 4x⁴y
Answer: 120
