Let the length be l
Then, 
l *(l-3)= 88
l²-3l =88
l²-3l-88=0
l²-11l +8l -88 =0
l(l-11) + 8(l-11) =0
(l+8)(l-11)=0
As, l can't be negative, length=11cm and width=(l-3)=11-3 =8 cm

If the side of a rectangular prism is doubled, how would this affect the area? How about the volume?
professor190 [17]

Answer:

Step-by-step explanation:

The area will be increased by 4 times  and volume will be increased by 8 times

Area of rectangular prism = 2 (lb+bh +hl)

When sides are doubled, Area = 2 (2l * 2b +2b *2h + 2h*2l)

                                                     = 4 * 2 (lb+bh +hl)

Volume  of rectangular prism = lbh

When sides are doubled,  Volume = 2l * 2h * 2b = 8 lbh

Calculate the average rate of change for the given function, from x = −3 to x = 7.
emmainna [20.7K]

Answer:

The average rate of change for the given function, from x = −3 to x = 7 will be:

  • Average rate = -5

Step-by-step explanation:

Given the table

x                      f(x)

-3                     50

3                      10

7                       0

As the interval is from x = -3 to x = 7.

so

at x₁ = -3, f(x₁) = 50

at x₂ = 7,  f(x₂) = 0

Using the formula to determine the average rate of change at which the total cost increases will be:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                       = [0 - 50] / [7-(-3)]

                      = [-50] / [7+3]

                      = -50 / 10

                      = -5

Therefore, the average rate of change for the given function, from x = −3 to x = 7 will be:

  • Average rate = -5
