Answer:

B) a= -1, b=5, c=0

Step-by-step explanation:

This is a quadratic equation.

From the form given y=ax^2+bx+c, it can be deduced that a, b and c are the coefficient of x^2, x and the constant respectively.

As such, when y=ax^2+bx+c is compared with

y= -x^2+5x,

a = -1, b = 5 and c = 0

Hence option B) a= -1, b=5, c=0 is right.

A gift box in the shape of a rectangular prism measures 8 inches by 8 inches by 10 inches what is the least amount of wrapping p

Phantasy [73]

The first thing we must do for this case is to find the surface area of the rectangular prism.
We have then:
A = 2 * (l * h) + 2 * (h * w) + 2 * (w * l)
Where,
w: width
l: long
h: height
Substituting values we have:
A = 2 * (10 * 8) + 2 * (8 * 8) + 2 * (8 * 10)
A = 448 in ^ 2
Answer:
the least amount of wrapping paper needed to wrap the gift box answer is:
A = 448 in ^ 2
