Answer:
Step-by-step explanation:
Following PEMDAS:

F(x) = x² - 1
f(2a) = 35
f(2a) = (2a)² - 1 = 35
4a² - 1 = 35
4a² = 35 + 1
4a² = 36
a² = 36/4
a² = 9
a = √9
a = +3 or -3.
Answer
Expressions 4(x+5) and 5(x+4) are Equivalent
Expressions 5(2m+2) and 10m+10 are not equivalent
Step-by-step explanation:
Heres why,
4(x+5) and 5(x+4)
4 times x =4x, so multiply 4x by 5 which should give you 20.
and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.
5(2m+2) and 10m+10
times 5 to 2m to get 10m and times 10m by 2 to get 20.
10m+10 = 1 which they are not equivalent
