Answer:
2
we know that and means adding so.
from the question
2+2/3-1+1/3
=1+2/3+1/3
=(3+2+1)/3
=6/3
=2
One foot = 12 inches.
32 feet = x inches
x/12=32/1
so
x=12*32/1 inches per second^2
4 x^2 + 28 x + 49 = 0
Divide both sides by 4:
x^2 + 7 x + 49/4 = 0
Write the left hand side as a square:
(x + 7/2)^2 = 0
Take the square root of both sides:
x + 7/2 = 0
Subtract 7/2 from both sides:
Answer: x = -7/2
Answer:
8x + 22
