The area of a face of a cube is 144cm^2 . find its volume​

Mathematics
1 answer:
love history [14]3 years ago
5 0

Step-by-step explanation:

1 face area = length x width (aka length x length since cube)

therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)

volume = length x width x height = 12 x 12 x 12 = 1728cm^3

Which of the following values for x and y make the equation 4x+2y+3=19 true?
Aleksandr-060686 [28]

Answer:

x = 3, y = 2

Step-by-step explanation:

Substitute the values of x from each alternative in the previous <em>question</em>, then solve for y. This is depicted below.

  • <em>A. y = -7, x = 5, 4(5) + 2y + 3 = 19</em>
  • <em>B. y = 0 and x = 4, 4(4) + 2y + 3 = 19</em>
  • <em>C. y = 2 and x = 3, 4(3) + 2y + 3 = 1</em>
  • <em>D. y = 4, x = 2, 4(2) + 2y + 3 = 19</em>

Only the third option has a y value that is <em>comparable</em> to the value in the computations, according to the calculations.

As a result, the letter C is the correct response.

Please help I don’t know the answer :(
gogolik [260]

Answer:

When x=8, y=-6. When x=10, y=0

Step-by-step explanation:

y=3x-30\\x^2+y^2=100

You can plug the given y value into the second equation to get:

x^2+(3x-30)^2=100\\x^2+9x^2-180x+900=100\\10x^2-180x+800=0\\10(x^2-18x+80)=0\\10(x-8)(x+10)=0\\x= 8, 10\\y= -6, 0

Hope this helps!
