disa [49]

Answer:

First: 12 feet

Second: 11 feet

Third: 14 feet

First side of the triangle= x+1

Third side of the triangle= x+3

x+x+1+x+3 = 37

3x+4 = 37

3x = 37-4

3x = 33

x = 11

First side of the triangle= (11)+1

= 12

Second side of the triangle= 11

Third side of the triangle= (11)+3

= 14

What is the volume of a cube with three 1/3 inch sides
boyakko [2]

Answer:

(1/27) in^3

Step-by-step explanation:

"sides" is inappropriate here.  You meant "a cube with three edges each 1/3 inch long."

V of cube:  V = s^3, where s:  side length

Here, V = (1/3 in)^3 = (1/27) in^3

Note:  all cubes have 6 (six) sides, including this one with 6  1/3 in sides.

How do you solve f (x)=-3 (x+2)+2
Allushta [10]

Answer:

−1/3y+−4/3

Step-by-step explanation:

We need to solve for x.

How? Easy! :D

Step one: Flip the equation. (In class we call it the 'flip-flop'.) When you do this, you should have your equation look like this:

−3x−4=y

Step two: Add 4 to both sides of the equation. When you do this step, your problem should look like this:

−3x−4+4=y+4

−3x=y+4

Step three: Divide both sides by -3.

-3x/-3 = y+4/-3.

Step four: Wrap-up. What the answer is.

x = -1/3y + -4/3

Final step: OUR ANSWER!

x = -1/3 + -4/3

Hope this helped! :D
