What is the sum of 2x^2 and 2x^3

jeyben [28]

For this case we have the following expression:

$2x ^ 2 + 2x ^ 3$

The terms are not similar, so they cannot be added.

<em>Examples of similar terms:</em>

$x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4$

Then, the expression given can only be rewritten as:

$2 (x ^ 2 + x ^ 3)$

This is taking common factor 2 to both terms.

Answer:

$2 (x ^ 2 + x ^ 3)$

Rectangle (left): A = 9 x 7 = 63

Rectangle (right): A = 2 x 10 = 20

Quarter circle: A = (1/4 x 3.14 x 3^2) = 7.065

A = 63 + 20 + 70.65

A = 90.065 square feet
