Answer:
x + 7
Step-by-step explanation:
x2 + 4x − 21
set equal to 0
x2 + 4x − 21 = 0
factor
(x - 3) (x + 7)
x2 + 11x + 28
set equal to 0
x2 + 11x + 28 = 0
factor
(x + 4) (x + 7)
Answer:
972π in³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ← r is the radius
Here r = 9, thus
V = π × 9³ = π × 729 ( divide 3 and 729 by 3 )
= 4π × 243
= 972π in³

Answer:
There are 8 faces on the figure.
There are two of the same sides so we can multiply that by 2. That side equals 76 in. 76 x 2 = 152.
Then, there is another side that equals 4 x 4 which is 24.
Another side equals 4 x 6 which is 24.
Another one equals 6 x 6 which is 36.
Another side equals 6 x 6 which also equals 36.
Another side equals 10 x 6 which is 60.
The last side is 10 x 6 which equals 60.
Which should add up to 392 in.
