7.5 is 30 percent of 25 because
25 divided by 10 is 2.5 times 3 is 7.5
The length of a rectangle:
L = 2 W + 5
The perimeter:
P = 2 L + 2 W
130 = 2 · ( 2 W + 5 ) + 2 W
130 = 4 W + 10 + 2 W
130 - 10 = 6 W
120 = 6 W
W = 120 : 6
W = 20 in
L = 2 · 20 + 5
L = 40 + 5
L = 45 in.
Finally the area:
A = L · W
A = 20 · 45
A = 900 in²
Answer:the range of the rectangle would be ∞1.0∞
Step-by-step explanation:
Answer:
Step-by-step explanation:
x = 2 is a vertical line; all values of y are possible.
y ≤ -3 is a region which includes -3 and all numbers less than -3.
So: draw a light line x = 2. Then draw a dark line at y = -3. Now darken the line x = 2 for (-infinity, -3].
