Answer:

The product of the 3a(8a – 6b) is 24a² - 18ab .

Step-by-step explanation:

As the expression given in the question.

= 3a(8a – 6b)

This can be written as

= 3a × (8a – 6b)

Simplify multiply 3a with 8a and – 6b .

Than

= 3a × 8a – 3a × 6b

= 24a² - 18ab

Therefore the product of the 3a(8a – 6b) is 24a² - 18ab .

The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface

never [62]

Answer:

$2\sqrt{2}\ ft\ longer$

Step-by-step explanation:

Area Of A Cube

Suppose a cube with side length s, the area of one side is

$A_s=s^2$

Since the cube has 6 sides, the total area is

$A=6A_s=6s^2$

But if we have the area, we can solve the above formula for s to get

$A=6s^2$

$\displaystyle s=\sqrt{\frac{A}{6}}$

We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths

$\displaystyle s_1=\sqrt{\frac{1,200}{6}}=\sqrt{200}$

$\displaystyle s_1=10\sqrt{2}\ ft$

$\displaystyle s_2=\sqrt{\frac{768}{6}}=\sqrt{128}$

$\displaystyle s_2=8\sqrt{2} ft$

The difference between them is

$10\sqrt{2}\ ft-8\sqrt{2}\ ft=2\sqrt{2}\ ft\approx 2.83\ ft$

The side of the cube with area 1,200 square inches is $2\sqrt{2}\ ft$ longer then the side of the cube with area 768 square inches

Carlos has scored 83, 81, and 73 on his previous three tests. What score does he need on his next test so that his average (mean

disa [49]

Answer:

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = $\frac{83+81+73+x}{4}$ = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95
