b.5x + 12x = 30
c.5x + 30 = 12x
d.12x + 30 = 5x
Answer:
c.5x + 30 = 12x
Step-by-step explanation:
Given :Mrs. Ramiriz is making pies to sell at the local farmer’s market. It costs her $5 to make each pie, plus a one-time cost of $30 for baking supplies. She plans to sell the pies for $12 each.
To Find: Which equation can be used to find the number of pies she needs to sell to break even?
Solution:
Let no. of pies be x
It cost her $5 to make each pie
so, cost of making x pies = 5x
Since there is a one-time cost of $30 for baking supplies.
So, total cost for her is 5x+30
If she sells each pie for $12
Then cost of pies = 12x
Now equation can be used to find the number of pies she needs to sell to break even:
5x+30=12x
The polynomial 16a² - 4a + 4a - 1 can be simplified to a difference of squares
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
The difference of two squares is given by:
a² - b² = (a + b)(a - b)
Hence:
16a² - 4a + 4a - 1 = 4a(4a - 1) + 1(4a - 1)
= (4a + 1)(4a - 1)
The polynomial 16a² - 4a + 4a - 1 can be simplified to a difference of squares
