Find the perimeter of the rectangle using the formula 4.2 6.7 perimeter=2l+2w

We are given dimensions of the rectangle:

Length= 4.2 units  and width = 6.7 units .

Given formula of perimeter = 2L + 2W.

Plugging value of Length= 4.2 and width = 6.7 in above formula, we get

Perimeter = 2(4.2) + 2(6.7)

Multiplying 2 * 4.2 we get 8.4 and multiplying 2* 6.7 we get 13.4.

                = 8.4 + 13.4.

                = 21.8 units

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
