Answer:
The area of the rectangle = 50 cm^2.
Step-by-step explanation:
Let the shortest side of the rectangle be x cm.
Perimeter of the rectangle is:
2x + 2(x + 5).
Perimeter of the triangle = 3 * 2x.
As they have the same perimeter:
2x + 2(x + 5) = 3*2x
2x + 2x + 10 = 6x
6x - 2x - 2x = 10
2x = 10
x = 5 cm.
So the area of the rectangle = x(x + 5)
= 5 * 10
= 50 cm^2.
Answer:
8
Step-by-step explanation:
diameter is the radius times 2
Y = -x - 2.....in y = mx + b form, the m represents the slope and the b represents the y int. (and if u didnt already know, -x is the same as -1x)
so in ur equation, the slope is -1 and the y intercept is -2....or (0,-2)
so u would plot (0,-2) and use the slope of -1 to plot another point. Draw a line through the points.
Answer:
38+2x+125 = x+163
subtract x from both sides
38+x + 125 = 163
38+125 = 163
163+x = 163
subtract 163 from both sides
x=0
