Might fail math, need desperate understandinf these problems

the area of a rectangular parking lot can represented by
a=4x + 200x

what is the expression for the length and width of the parking lot

find an expression for the perimeter of the parking lot

find the area of the parking lot if x=50m

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

answer by jkismyhusbandbae:

a) how close a measured value is to the actual (true) value.

  measure of length.   there are 12 inches in a foot, and 36 inches in a yard.   one inch is exactly 2.54 centimeters.

accuracy is how close something is to an actual answer but it is not exactly correct.
