Answer:
9 and 4 or D
Step-by-step explanation:
If you're not quite sure how to solve, let's find the answer by process of elimination.
If the area of a rectangle is 36 square inches, we can try option one.
7 * 6 = 42, not 36, so option A is incorrect.
Option two:
12 * 3 = 36 so option B is correct.
Option 3:
10 * 3 = 30 so option C is incorrect
Option 4:
9 * 4 = 36 so option D is correct
Now for perimeter:
9 + 4 + 9 + 4 = 18 + 8 = 26.
12 + 12 + 3 + 3 = 24 + 6 = 30
Thus, an answer of 9 and 4 is correct.
Answer:
She can be a member for 8 months
Step-by-step explanation:
Let x be the number of months
30 + 10.5(x) = 114
30 + 10.5x = 114
10.5x = 114-30
10.5x = 84
x = 84/10.5
x = 8 mints
