Answer:
Step-by-step explanation:
<u>Given sides of a rectangle</u>
- Length: l =4 − 7(3x + 4y)
- Width: w = 3x(−2y)
<u>Perimeter of rectangle</u>
<u>Using the given values</u>
- P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
- 2( 4 - 21x - 28y - 6xy) =
- 8 - 42x - 56y - 12xy
Answer:
9x+6
Step-by-step explanation:
I think by equivalent, you mean solve it.
5x+(x+6)+3x
5x+x+6+3x, open the parenthesis
9x+6, add up the like terms
Answer:
x=2 x=-4
Step-by-step explanation:
x^2 +2x-8=0
Factor
What numbers multiply to -8 and add to 2
-2*4 = -8
-2+4 =2
(x-2) (x+4) =0
Using the zero product property
x-2 =0 x+4 =0
x-2+2=0+2 x+4-4=0-4
x=2 x=-4
