Answer: 300 square feet
Step-by-step explanation:
length of walkway = 20 + 2x
width of walkway = 15 + 2x
A(x) = (20 + 2x)(15 + 2x)
A(x) = 300 + 30x + 40x + 4x2
A(x) = 300 + 70x + 4x2
The answer is (2 1/2) but without the brackets
Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
