PLEASE! 10 POINTS! For what number A does the equation 3Ax - 24 = 5x - 9 + x have no solutions for x?
Gala2k [10]

Answer:

3Ax-6x = 15

3x(A-2)=15

If A were 2, the left side of the equation would be 0 and it wouldn't equal 15 no matter what the value of x is. So A is 2

The length of the rectangular prism shown below is three times the width. The height and the width are the same. If the volume o
Liono4ka [1.6K]

Answer: the length of the prism is 9cm

Step-by-step explanation:

The formula for determining the volume of a rectangular prism is expressed as

Volume = length × height × width

Volume = LWH

The length of the rectangular prism is three times the width.. It means that

L = 3W

The height and the width are the same. This means that

H = W

Therefore,

Volume = 3W × × W × W = 3W³

If the volume of the prism is 81 cubic centimeters, it means that

81 = 3W³

Dividing through by 3, it becomes

81/3 = 3W³/3

W³ = 27

Taking cube root of both sides, it becomes

W = 3

Therefore, the the length of the prism would be

L = 3W = 3 × 3

L = 9 cm
