Answer:

x=22

Step-by-step explanation:

Label the intersection point between K and J as H. Similarly, label the intersection point between K and L as M.

The triangle proportionality theorem states that HK/JK=MK/LK.

Substitute the values into the equation above. HK=36-6=30. LK=2x-4+8=2x+4.

30/36=2x-4/2x+4

Now, solve:

30(2x+4)=36(2x-4)

60x+120=72x-144

12x=264

x=22

Write a simplified polynomial expression in standard form to represent the area of the rectangle below.

Stells [14]

Answer:

$5x^{2} -18x-8$

Step-by-step explanation:

The formula for area of a rectange is lw, where l is length and w is width. Since x-4 and 5x+2 are the sides, we can multiply them together to give us the area. We do (x-4)(5x+2). We use the FOIL method (First Outside Inside Last) and get 5x^2-18x-8.

Answer:

True

Step-by-step explanation:

Cuz if u substitute (3,-3/2) it would work

Y = 1/2x - 3

-3/2 = 1/2(3)-3

-3/2 = 1.5 - 3

-3/2 = -1.5

& -3/2 is -1.5 as a decimal lol
