Step 1: Make sure that the trinomial is written in the correct order; the trinomial must be written in descending order from highest power to lowest power.
Step 2 : Decide if the three terms have anything in common, called the greatest common factor or GCF. If so, factor out the GCF. Do not forget to include the GCF as part of your final answer.
Step 3 : Multiply the leading coefficient and the constant, that is multiply the first and last numbers together.
Step 4 : List all of the factors from Step 3 and decide which combination of numbers will combine to get the number next to x.
Step 5 : After choosing the correct pair of numbers, you must give each number a sign so that when they are combined they will equal the number next to x and also multiply to equal the number found in Step 3.
Step 6 : Rewrite the original problem with four terms by splitting the middle term into the two numbers chosen in step 5.
Step 7 : Now that the problem is written with four terms, you can factor by grouping.
Answer: y=3x+12
explanation: just add the 3x to the 12
Answer:
The rate is usually given as a percent.
To find the discount, multiply the rate by the original price.
To find the sale price, subtract the discount from original price.
Step-by-step explanation:
The rate is usually given as a percent.
To find the discount, multiply the rate by the original price.
To find the sale price, subtract the discount from original price.
Answer:
T= 20 + 35h
Step-by-step explanation:
Giving the following information:
An electrician charges $35 per hour, h, plus a $20 fee for driving to your house.
The $20 fee is a <u>fixed cost. It will remain constant.</u>
The $35 fee acts as a <u>variable cost. It varies with the number of hours required to do the job.</u>
<u>To calculate the total cost (T), we need to use the following formula:</u>
T= 20 + 35h
h= number of hours.
