8x^2-5x-2
method
open bracket
6x^2-2x-3+x^2-3x+1
collect like terms
6x^2+2x^2-3-3x+1
8x^2-3-3x+1
again collect like terms
8x^2-2x-3x-3+1
8x^2-5x-3+1. (-×-=+ addition but keeping sign minus
8x-5x-2. (-×+=-)
Answer:
B. 2x + 7
Step-by-step explanation:
I can see where this is tough, lets go through it. Polynomials that are factored need to be able to multiply back into themselves. When looked at a polynomial, you can find a common multiplier for both, but we already have those. The common multipliers are what goes outside of the parenthesis. Now you just need to find what's inside. The numbers inside are going to be the numbers that multiply back to the numbers above. You can go by process of elimination to get rid of options. First, you will do 5 * 2 to get 10, meaning you can remove A and C. Then you see that you have to get to the third power on the 10, and get to x on the 4. This means you will have to have 1x on the first number of the set to ensure you get both of those numbers.

Answer:
#1.---60% #2.---$12.60 per hour
Step-by-step explanation:
#1. Since It was originally $50 you have 50% already, so what I did was I multiplied 50 by 2. this got me 100 which is a simpler way to calculate by. 50 to 80 dollars is a $30 change, so multiply that by 2 and you get 60. 60 will be your percent of change. You can double check this by multiplying 50 by .60, the answer will be 30 and 50+30=80
#2 Since Tyler starts off with $12 per hour with a 5% increase you will need to multiply 12*.05 this will get you the answer of 0.6 you then need to add $12, since that was his original payment. 12+0.6=12.60, so his final payment would by $12.60 per hour
