Option C: 5 x(4 x+7)(3 x+2) is the possible expressions for length, width and height of the prism.

Explanation:

The volume of the rectangular prism is 60 x^{3}+145 x^{2}+70 x

To determine the length, width and height of the rectangular prism, let us factor the expression.

Thus, factoring 5x from the expression, we have,

5 x\left(12 x^{2}+29 x+14\right)

Let us break the expression 12 x^{2}+29 x+14 into two groups, we get,

5x[\left(12 x^{2}+8 x\right)+(21 x+14)]

Factoring 4x from the term 12 x^{2}+8 x , we get,

5x[4 x(3 x+2)+(21x+14)]

Similarly, factoring 7x from the term 21 x+14 , we get,

5x[4 x(3 x+2)+7(3x+2)]

Now, let us factor out 3x+2, we get,

5 x(4 x+7)(3 x+2)

Hence, the possible expressions for length, width and height of the prism is 5 x(4 x+7)(3 x+2)

Therefore, Option C is the correct answer.

Look at this inequality: 12−4x ≤ 20
SSSSS [86.1K]

Answer: The last line is the answer

12 - 4x <u><</u> 20

20 - 12 = 8

-4x = 8

-4/4 = 8/-4

x = -2

New inequality: x <u>></u> -2

(If you dont care much for the explanation)

ANSWER IS
$131.35


If 1 liter of milk is $17 3/4 we just need to find the cost for 7 2/5.
Since we’re working with money we have to turn the $17 3/4 and 7 2/5 into a decimal so its ($17.75) and 7.40

Anyways we multiply those numbers to find the cost of 7 2/5 liters
( 17.75 x 7.40) and the answer is $131.35
