Answer:
Length is 15 inches
Width is 8 inches
Step-by-step explanation:
A = L*W
the Width = L-7
120 = L (L-7)
120 = L^2-7L
subtract 120 from each side
0 = L^2 - 7L - 120
(L-15) (L +8 )
so L = 15 inches
and W = 15-7 = 8 inches
check your answer: does 15*8 = 120? yes!
-1 - 10n is a simple version
Answer:
g = 
Step-by-step explanation:
Given
t = v + 
Multiply through by g to clear the fraction
tg = vg + k ( subtract vg from both sides )
tg - vg = k ← factor out g from each term on the left side
g(t - v) = k ← divide both sides by (t - v)
g = 
Answer:
It would be 3C, 2C, 0C, -6C, -7C, -9C, then -18C
Step-by-step explanation:
This is because the larger a postive number is above 0, the greater it is. Along with this, the smaller a negative number is, the less it is.
1 foot = 12 inches
(1 foot) x (1 foot) = (1 foot)² = (12 inches) x (12 inches) = 144 inches²
