Find the dimensions of a triangle given the base, height, and area. b=8 inches h=7 inches A=28 square inches

Step-by-step explanation:

The area of a triangle of base 8 in, and height 7 in, is

A = (1/2)(base)(height) = (1/2)(8 in)(7 in) = 28 in^2.  This matches the given 28th in^2.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
