Answer:

26x³ - 12x² + 5x + 7

Step-by-step explanation:

(2x³ - 3x + 11) - (3x² + 1) x (4 - 8x)
2x³ - 3x+11 - (12x² - 24x³ + 4 - 8x)
2x³ - 3x + 11 - 12x² + 24x³ - 4 + 8x
26x³ + 5x + 7 - 12x²

= 26x³ - 12x² + 5x + 7

2. You are trying to determine which box of Honey Nut Cheerios to buy, The Family Size box weighs

Katyanochek1 [597]

Answer:

Mega Size

Step-by-step explanation:

Given

Family Size

$Weight = 19.5\ oz$

$Cost = \$3.64$

Mega Size

$Weight = 29.4\ oz$

$Cost = \$4.98$

Required

Determine which has a better value

First, we calculate the unit rate of both.

$Unit\ Rate = \frac{Cost}{Weight}$

For the family size:

$Unit\ Rate = \frac{\$3.64}{19.5\ 0z}$

$Unit\ Rate = \$0.187\ per\ 0z$

For the mega size:

$Unit\ Rate = \frac{\$4.98}{29.4\ 0z}$

$Unit\ Rate = \$0.169\ per\ 0z}$

By comparing the unit rates, the mega size has a better value because it costs cheaper per unit rate

PLEASE EXPLAIN THIS 6th GRADE MATH

8090 [49]

Answer:

$b = l\times w$ to guarantee that both formulas are the same.

Step-by-step explanation:

Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that $l,w,h$ have length units, whereas $b$ have area unit, that is, the square of length.

Hence, $b = l\times w$ to guarantee that both formulas are the same.
