First we need to combine like terms. so we move the like terms to different parts of the equation:
5x -3x = 66-20
then we combine the like terms:
2x= 46
bow we divide both sides by 2 to isolate x:
2x ÷2= 46 ÷2
x= 23
any questions? just ask. I hope this helped! :)

Answer:

  420 mm³

Step-by-step explanation:

The volume is given by the formula ...

  V = Bh

where B is the area of the triangular base, and h is the height.

The triangular base area is given by the formula ...

  A = 1/2bh

  A = 1/2(10.5 mm)(10 mm) = 52.5 mm²

Then the volume of the prism is ...

  V = (52.5 mm²)(8 mm) = 420 mm³

What are the coordinates of the intersection of the graphs of 3x - y^2 = 12 and y = -3
inessss [21]

Answer:

(7,-3)

Step-by-step explanation:

y = -3

substitute in the first equation

3x - y^2 = 12

3x - (-3)^2 = 12

3x - 9 = 12

3x = 12 + 9

3x = 21

x = 7
