What is the perimeter of the figure to the right if x = 1? A. 3
B. 10
C. 13
D. 28
F. 51
5x-2

perimeter = 26

Step-by-step explanation:

perimeter of a rectangle = 2L + 2W

where:

L = 5x² - 2

W = 7 + 3x

Let x = 1

find:  Perimeter

substitute values into the formula:

P = 2(5 * 1² - 2) + 2(7 + 3 * 1)

P = 2(3) + 2(10)

P = 6 + 20

P = 26

therefore,

the perimeter = 26

178 sundaes were sold in July.

To calculate a percentage, we convert to a decimal by dividing by 100. So 23% = 0.23

145 x 0.23 = 33.35 This is how many more sundaes were sold in July than June. We need to add the 145 sold in June to the increased number to find July’s total.
145 + 33.35 = 178.35

You can’t sell .035/ roughly a third of a sundae, so we round to the whole number.
