$128 is the answer.
The carton has a volume of 512 square inches because since it is a cube 8 inches tall, that is also the length and width. Each plastic cube is 1 square inch, so 512 cubes will fit. All the cubes in total will cost $128 .

If the carton is shaped like a cube, the length will be equal across all sides.
So every side length (length, width, height) is 8 inches.

Find the volume of the carton (cube) to see how many colored plastic cubes fit into the carton.

Volume of a cube: length x width x height, or side length cubed.

Plug 8 inches into the formula: 8 x 8 x 8 = 512 inches³

The carton can fit 512 cubes. If each cube is 25 cents each, multiply 512 by 0.25 to get how much it would cost to buy all the cubes.

512 x 0.25 = 128

It would cost $128 to buy all the cubes in the carton.

Step-by-step explanation:

-15.4b + 13 = 9b-41.9

-15.4b-9b = -41.9 - 13

-24.4b= -54.9

divide both side by -24.4

-24.4b/-24.4 = -54.9/-24.4

minus divide by (-)

b= 2.25

What equation results from completing the squre and then factoring x^2+10=15

nlexa [21]

For this case we must complete squares:

$x ^ 2 + 10x = 15$

We add the square of half the coefficient of the term "x",

$(\frac {b} {2a}) ^ 2$ on both sides of the equation:

$x^2+10x+(\frac {10} {2 (1)}) ^ 2 = 25 + 15\\x ^ 2 + 10x + 5 ^ 2 = 25 + 15$

According to the perfect square trinomial we have:

$(a + b) ^ 2 = a ^2 + 2ab + b ^ 2$

Rewriting the expression we have:

$a = x\\b = 5\\(x + 5) ^ 2 = 25 + 15\\(x + 5) ^ 2 = 40$

ANswer:

$(x + 5) ^ 2 = 40$
