Answer:

$32x^3+4x^2+41x-35$

Step-by-step explanation:

Given expression is,

$(4x^2+3x+7)(8x-5)$

Using the distributive property,

$(4x^2+3x+7)(8x)-(4x^2+3x+7)(5)$

Again by distributive property,

$4x^2(8x)+3x(8x)+7(8x)-4x^2(5)-3x(5)-7(5)$

$32x^3+24x^2+56x-20x^2-15x-35$

Combine like terms,

$32x^3+4x^2+41x-35$

No. of diners = 240

Musya8 [376]

Answer:

<u>We need to buy 3 cases of juice.</u>

Correct statement and question:

No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?

Source:

Previous question that you can search at brainly

Step-by-step explanation:

Let's calculate the number of cases of juice are required this way:

Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case

Replacing with the real values, we have:

Number of cases required = [(240 * 4)/48]/8

Number of cases required = [(960)/48]/8

Number of cases required = 20/8

Number of cases required = 2.5

<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>

Wangari plants trees at a constant rate of 1212 trees every 33 hours. Write an equation that relates pp, the number of trees Wan

igor_vitrenko [27]

Answer:

$p=4h$

Step-by-step explanation:

Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.

We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.

Let us find number of trees planted in 1 hour by dividing 12 by 3.

$\text{Number of trees planted in 1 hour}=\frac{12\text{ plants}}{3\text{ hour}}$

$\text{Number of trees planted in 1 hour}=4\frac{\text{ plants}}{\text{ hour}}$

We can represent this information as: $p=4h$

Therefore, the equation $p=4h$ relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
