Answer:
Replace the variable x with −1
in the expression.
f(−1)=−(−1)²−1
Simplify −(−1)²−1.
Remove parentheses.
−(−1)²−1
Multiply −1 by (−1)²
by adding the exponents.
(−1)³−1
Raise −1 to the power of 3.
−1−1
Subtract 1 from −1.

What do you need help with
Answer:
d
Step-by-step explanation:
The similar sides always have to be paired up or with the number that's on the same rectangle.
a is good because 2 and m are on the same rectangle just like 3 and 5
b is good because m corresponds to 5 just as 2 does to 3
c is good for the same reason as b
d doesn't fit the criteria
also if you solve for m using every proportion, a, b, and c all end as m=10/3 but d had m=6/5
Answer:
x = 
Step-by-step explanation:
Given
- 19 + 3x - 11 + 2x = 2 ← simplify left side
5x - 30 = 2 ( add 30 to both sides )
5x = 32 ( divide both sides by 5 )
x = = 6.4
