Question

Art An art teacher made a copy of a small painting. To make the painting easier to see, the teacher

enlarged the area of the painting by 30%. Let x represent the area of the original painting. The
expression below is one way to represent the area of the new painting. Find two equivalent
expressions that would give the area of the new painting.
X +0.3x


Which expressions will give the area of the new painting? Select all that apply.
A 130x
B. X + 30x
C. X(1 +0.3)
D. 0.3x
E. 1.3x

Answer 1

C and E

Explanation:

C : x(1+0.3)

if we break the bracket, we get : x + 0.3x, which is 1.3x = 30% larger
e is already 1.3x, so we can conclude c and e is the two equivalent expressions
