Allisa [31]4 years ago

Answer:

(7,0) and (1,0)

Step-by-step explanation:

To find the x-intercepts, we set the equation equal to 0 and solve. So, we set x²-8x+7 equal to zero and solve. This can be factored as (x-7) and (x-1).

We have (x-7)(x-1)=0

x-7=0 x-1=0

x=7       x=1

X-intercepts: (7,0) and (1,0)

Item 1 Find the volume of the prism. A rectangular prism with length of start fraction 4 over 5 end fraction millimeter, width o
nirvana33 [79]

Answer:

The volume of the rectangular prism is 3/20 (or 0.15) mm³.

Step-by-step explanation:

The volume of the rectangular prism can be calculated as follows:

V = l*w*h     (1)

Where:

l: is the length = 4/5 mm

w: is the width = 1/2 mm

h: is the height = 3/8 mm  

By entering the values of l, w, and h into equation (1) we can find the volume:

V = l*w*h = \frac{4}{5} mm*\frac{1}{2} mm*\frac{3}{8} mm = \frac{3}{20} mm^{3} = 0.15 mm^{3}

Therefore, the volume of the rectangular prism is 3/20 (or 0.15) mm³.

I hope it helps you!

To find the volume of a rectangular prism, you can use the formula of V = l w h. A rectangular prism has a volume of 60 cubic ce
anzhelika [568]

Answer:

W = 4

Step-by-step explanation:

The nice thing about algebra is that you can look for any variable in an equation as long as you have the number for the other variables.

1. Write our the equation. V = l w h

2. Put in as many numbers as you can. 60 = 5 w 3

3. Isolate the variable. To do that perform the mathematical opposite to the target on both sides. So to get rid of five, we have to divide it on both sides of the equal sign.

60/5 = w 3

12/3 = w

4 = w

The width is 4cm
