Step-by-step explanation:
Answer:
1) D.
2) E. The coefficient of is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form , where is the grade of the polynomial. In this case, the only equation that satisfies this definition is:
Correct answer: D
2) Let , we proceed to expand the expression by algebraic means:
We see that coefficients for and are -16 and 0, respectively. Hence, the incorrect answer is E.
Answer:
the width is ≤ 38 feet
Step-by-step explanation:
the perimeter of a rectangle is given by the relation : 2*( length + width)
P ≤ 120
2 (L + W) ≤ 120
L + W ≤ 60 ,,, L = 22
22 + W ≤ 60
W ≤ 38 feet
