Answer: x = -9/ addition property of equality
Explanation: In this problem, we're given that x - 7 = -16 and we're asked to solve the equation and explain which equality we used.
The first statement we have will be
the given statement which is x - 7 = -16.
Now, we just solve the equation.
Our first and only step will be to add 7 to both sides.
Then, we find that x = -9.
The property we used here was the addition property of equality.
This property tells us that we can add the same quantity,
or equal quantities, to both sides of an equation.
Answer:
B
Step-by-step explanation:
this equation is in the form of ax^2+bx+c
so a is 4, b is -9, and c is 8
Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
use w=12 to solve for l
l=2(12)
l=24
