Brad has two lengths of copper pipe to fit together one has a length of 2 5/12 feet and the other has a length of 3 7 12 ft how

leva [86]

To find the total length of the two copper pipes, we need to add them together.

2 5/12 + 3 7/12 = 5 12/12

Since 12/12 = 1 or a whole, we can simplify this further.

5 12/12 = 6

Hope this helps!

-3x(x+8)+x+2(9-x-x^2) please show solving steps

Flauer [41]

Answer:

-5x^2 - 25x + 18

Step-by-step explanation:

-3x ( x + 8 ) + x + 2 ( 9 - x - x^2 ) ( original equation )

-3x^2 - 24x + x + 18 - 2x - 2x^2 ( distribute )

-3x^2 - 2x^2 - 24x + x - 2x + 18 ( order them based on the variables . )

( -3x^2 - 2x^2 ) (- 24x + x - 2x ) ( + 18 ) ( just separated them not a part of solving !! )

-5x^2 - 25x + 18 ( solved , and the answer :) )

Hope its helps !!!

The equation for the circle below is x ^2 + y^2 = 100. what is the length of the circles radius?

Ganezh [65]

Answer: 10 units.

Step-by-step explanation:

The equation of the circle in Center-radius form is:

$(x - h)^2 + (y - k)^2 = r^2$

Where the center is (h,k) and "r" is the radius.

The equation of the circle given is:

$x ^2 + y^2 = 100$

You can observe that is written in Center-radius form.

Then, you can identify that:

$r^2=100$

Knowing this, you need to solve for "r" to find the lenght of the radius.

This is:

$r=\sqrt{100}\\\\r=10$

Therefore, the lenght of the radius is 10 units.
