Answer:
Step-by-step explanation:
11.-3(2x-8)=-12
-6x+24=-12
-6x=-12-24
x=-36/-6
x=6
12.4(6+2x)=0
24+8x=0
8x=0-24
x=-24/8
x=-3
13.3x+2x+6=-15
5x+6=-15
5x=-15-6
x=-21/5
14.4=-2(x+3)
4=-2x-6
4+6=-2x
10/-2=x
-5=x
15.27=46+2x-x
27=46+x
27-46=x
-19=x
Answer:

Step-by-step explanation:

Add 2 to both sides:


Subtract 7x from both sides:


Divide both sides by -1:


Answer:
A
Step-by-step explanation:
Hi
Answer:
width=x
length=5x
area= 300ft2
area=lxb
300=5x(x)
300=5x^2
x^2=60
x=7.74
7.74(5)=38.7
dimensions are 38.7ft by 7.74 ft
