Answer:
x=2
Step-by-step explanation:
28−(3x+4)=2(x+6)+x
We need to use the distributive property for the right side.
28−3x−4=(2)(x)+(2)(6)+x)
28−3x−4=2x+2+x
−3x+24=3x+12
From here we need to subtract 3x from both side.
−3x+24−3x=3x+12−3x
6x+24=12
Transfer +24 on the right side.
6x=12−24
6x=−12
Finally, divide both sides by −6
6x/-6 = -12/-6
x=2
Answer:
80 yards
Step-by-step explanation:
Using the area formula, A = lw, set up an equation where w represents the width.
The length can be represented by 3w because it is 3 times the width:
A = lw
300 = (3w)(w)
300 = 3w²
Solve for w:
300 = 3w²
100 = w²
10 = w
So, the width is 10 yards.
The length will be 30 yards since the length is 3 times the width.
Then, add the lengths and widths together to find the perimeter:
10 + 10 + 30 + 30
= 80
So, the perimeter is 80 yards
