Answer:
u know area of rectangle is length × breadth
therefore, area = (3x+4)×(7x-2)
= 21x²-6x+28x-8
= 21x²+22x-8
= d ans
Answer:
the awnser should be. slow and fast
X= # of eraser packages = 135
y= # of pencil packages = 85
cost = 2x + 5y = 695
# of items = x+y= 220
2x+5y=695
-2x -2y=-440
3y 255
----- = ------- y=85 x+(85) / 220
3 3 ----- -----
-85 -85
x=135
2(135) + 5 (85) ?695
270+425?695
695+695
The radius for number 2 is 9 inches the height is 20 inches. So you plug in those numbers into the equation to make: pi x 9^2 x 20 = 5089.38
The radius for number 3 is 10 inches and the height is 3 inches. So you plug in those numbers into the equation to make: pi x 10^2 x 3 = 942.48
The radius for number 4 is 5 inches and the height is 8 inches. So you plug in those numbers into the equation to make: pi x 5^2x 8 = 628.32
The radius for number 5 is 2 centimeters and the height is 5 centimeters. So you plug in those numbers into the equation to make: pi x 2^2(5) = 62.83
