Simplify the expression by combining like terms: 3x^2 + 12x+11+14x^2+8x+5

Step-by-step explanation:

Like terms have same variables with same exponents

3x² + 12x + 11 +14x² + 8x + 5

= 3x² + 14x² +    12x + 8x   + 11 + 5

= 17x² + 20x + 16

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

$12. that is my answer.
