Kelly buys a tarp to cover the area under her tent the tent is 4 ft wide and has an area of 31 square feet the tarp she bought is 5 1/3 ft by 5 3/4 feet can the tarp cover the area under kelly's tent draw a model to show your thinking

The tarp which Kelly bought can not cover r the area under Kelly's tent.

Step-by-step explanation:

Given that Kelly buys a tarp to cover the area under her tent the tent is 4 ft wide and has an area of 31 square feet the tarp she bought is 5 1/3 ft by 5 3/4 feet. we have to tell can the tarp cover the area under Kelly's tent.

Let us find the area of tarp whose dimensions are

The area of tarp which we calculate is less than that of area of tent which is given i.e . Hence, the tarp which Kelly bought can not cover r the area under Kelly's tent.

Also, given width of tent is 4 ft and the width of tarp is ⇒width of tarp is more so to cover the tent we have to make the width equal by cutting and attached to the length side which results into the wastage and needed more cloth for extra stitching.

Hence, the tarp which Kelly bought can not cover r the area under Kelly's tent.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
