To find the volume of a rectangular prism, Harris multiplies the area of the base times the height. The area of the base is (x + 4) square inches for
some value of x. The height is (2x + 3) inches. What is the volume, in cubic
inches, of the rectangular prism?

step-by-step explanation:

in which figure is point g a centroid

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
