Answer:
x+y=31
Step-by-step explanation:
I'd say that would be the equation bc it doesn't really give ages. Although I could be wrong so sorry if I am
width= 7m
Step-by-step explanation:
Area= L×W
L= (x+8)m
W=8m
105m²= (x+8)m × (x)m
105m²= x² + 8x
-x² - 8x + 105= 0
(x-7) (x+15) = 0
x= 7 x= -15
x=width = 7m
Answer:
Step-by-step explanation:
Perimeter is twice the sum of the length and width
P=2(L+W), in this case
P=2(4x+6+3x+4)
P=2(7x+10)
P=14x+20
Answer:
12150 ft^3
Step-by-step explanation:
= (45)(20)(10) + (350)(9)
= 9000 + 3150
= 12150 ft^3
