They are equivalent. They’re equivalent because 3+6=9 and 3(2+1) also equals 9 2+1 is 3 so you would have 3(3) and whatever number is in the parentheses you just multiply it with the other number and 3*3 is 9
Answer:
Explanation
Step-by-step explanation-
Find the perimeter:
8 1/2 + 8 1/2 + 6 1/3 + 6 1/3
17 + 12 2/3
29 2/3 feet.
Then, divide it by 2/3 for the panels:
29 2/3 =
89/3 / 2/3 =
19 7/9
Tada!
Substitute the values
-2(-2)^2+4(3)
First evaluate the exponent.
-2(4)+4(3)
Then evaluate multiplication.
-8+4(3)
-8+12
Then add.
