Answer:
C.
Step-by-step explanation:
1. Find the area part of the equation.
Area is base×height, so if we substitute 8 as the base and w as the height, <em>A=8w</em>
2. Find the perimeter of the equation.
Perimeter of a rectangle is 2(base + height), so in this case, it will be
<em>P=2(8 + w),</em> or C.
Answer:
a ≤ 2
Step-by-step explanation:
Simplify both sides of the inequality
42a + 48 ≤ 132
Subtract 48 from both sides
42a + 48 − 48 ≤ 132 − 48
42a ≤ 84
Divide both sides by 42
42a/42 ≤ 84/42
a ≤ 2
