the length of a rectangular deck is 5 feet longer than its width, x. the area of the deck is 310 square feet. which equation can be used to determine the width of the deck?

a) 0 = 2x^2 - 310
b) 0 = x^2 - 310
c) 0 = x^2 + 5x + 310
d) 0 = x^2 + 5x - 310

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
