Answer:
L = 18 and w = 16
Step-by-step explanation:
The area of a rectangle is found by A = l*w. Since the length here is 2 more than the width or 2 + w and the width is w, substitute these values and A = 288 to solve for w.
To solve for w, move 288 to the other side by subtraction. Then factor and solve.
Set each factor equal to 0 and solve.
w - 16 = 0 so w = 16
w + 18 = 0 so w = -18
Since w is a side length and length/distance cannot be negative, then w = 16 is the width of the rectangle.
This means the length is 16 + 2 = 18.
Answer:
y=8/11x-2
Step-by-step explanation:
in y=mx+b, the m= the slope, and the b=the y-intercept
Answer:
The perimeter is 41
Step-by-step explanation:
The perimeter of a shape is just the sum of all its sides added up. In this case, that would mean the perimeter is:
- 12 + 9 + 9 + 4.6 + 6.4 = P
- 30 + 11 = P
- 41 = P

Explanation:
So here we need to make a two-step changing factor.
This means that we first take
0.5
(something decreasing by
50
%
) times
0.8
(something decreased by
20
%
) which is
0.4
(something decreased by
60
%
