Answer:

23)

P = 20x^2 + 14xy^2

A = 70x^3y^2

24)

P = 8a^3b + 4ab

A = 4a^4b^2

25)

A = 18x^3y


Step-by-step explanation:

23)

P = 2(10x^2 + 7xy^2)

P = 20x^2 + 14xy^2

A = 10x^2 x 7xy^2

A = 70x^3y^2


24)

P = 2a^3b + 6a^3b  + 4ab

P = 8a^3b + 4ab

A = 1/2(2a^3b)(4ab)

A = 4 a^4 b^2


25)

A = 1/2(4xy+8xy)(3x^2)

A = 1/2(12xy)(3x^2)

A = 18x^3y

A business breaks even when the production costs are equal to the revenue. The expression 120+4x represents the cost of producin
nika2105 [10]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

The expression 120+4x represents the cost of producing x items. The selling price is $5 for each item.

<u>The net income formula:</u>

y= (5 - 4)x - 120

(5-4)= contribution margin per unit sold (x)

120= fixed costs

<u>To calculate the break-even point in units, we need to use the following formula:</u>

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 120 / 1

Break-even point in units= 120 units

Prove:

y= 1*120 - 120

y= 0
