A pet sitter originally charged clients $4 per hour of sitting plus a set fee of $20, or T(h) = 4h + 20. The sitter decided to double the fees. Which of the following functions represents the doubled fees?

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

it would be 6xy and -16xy.

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
