Answer:
4x-20
Step-by-step explanation:
you put the x's together and since its negative,you can make it -20 instead of +-20
Answer:
The volume of the solid is 180 cubic feet.
Answer:
48 mm ^ 2
Step-by-step explanation:
We know we have a cube of side x, therefore the volume of that cube will be equal to:
V = x ^ 3, because it is a cube and each side is the same.
Now the derivative of the volume with respect to the length (that is, x) would be:
dV / dx = 3 * (x ^ 2)
They tell us that x takes a value of 4, replacing we have:
dV / dx = 3 * (4 ^ 2) = 48
That is, 48 mm ^ 2 would be the value of dV / dx when x is equal to 4 mm.
-(7+8/100)
= -(7+4/50)
= -(7+2/25)
= -177/25
If it says five more than it means the 5 is after, and quantity of a number means it’s in parentheses so it would have to be C.
