Answer:
a
Step-by-step explanation:
a)
(b)
(c)
we are given
length is x+1
width is x+3
height is x-3
(a)
we can use volume formula
now, we can plug it
now, we can simplify it
we are given volume =1001
so, we can set V=1001
and then we can solve for x
now, we can factor it
we are given volume
so, we can set
x>=42
multiply by 7 on both sides
a= 6-b ,,, a+b=6
a+b= -2a-3,,, 3a+b=-3
2a=-9,,, a= -9/ 2
b= 21/2
D) f(x) = 6x
