Devin has started a lawn-care service. he will charge a mowing fee of $15 plus $2 per square yard of lawn. he also offers trimming service, at $10 plus $1 per yard of the perimeter. using x for the length of the lawn and y for the width of the lawn, which part of the expression represents the charge for the mowing?

15 + 2xy is the expression represents the charge for the mowing

Step-by-step explanation:

He will charge a mowing fee of $15 plus $2 per square yard of lawn.

Let x be the length of the lawn

y be the width of the lawn

Area of the lawn = length * width

Area = x*y square yards

Given that $2 per square yard

charge of mowing xy square yards = 2xy

Fixed charge is $15 so we add 15 as well

Expression becomes 15 + 2xy

i understand 100% 10/10 hit or miss?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
