The perimeter of a rectangular field is 100 feet. Which *COULD NOT* be the length and width of the perimeter?
Rina8888 [55]

Answer:

D) L=50 W=50

Step-by-step explanation:

Just "plug and chug" these numbers and see which doesn't work.

A is not it, 20+30=50 (then *2 because we need 4 sides not just 2) 50*2=100

B isn't it, 10+40=50*2=100

C ain't it either 49+1=50*2=100

D is the answer 50+50=100*2=200

Find the slope of the line that passes through:<br> (-4,7) and (-6, -4)
Yuri [45]

Answer:

\frac{11}{2} or 5.5

Step-by-step explanation:

In order to find the slope of a line using two points on a graph, you must use

y_2-y_1/x_2-x_1

Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5

The equation for the line would be \frac{11}{2}x+29
