- 2n - h(4rx - 6s) - 3rx + 3s =
= - 2n - h×4rx - h×(- 6s) - 3rx + 3s
= - 2n - 4hrx + 6hs - 3rx + 3s
= 2(3hs - 2hrx - 2) - 3(rx - s)
Answer:
21 years
Step-by-step explanation:
For this problem, you only need to divide 6,825 by 325.
6,825/325=21
21 years
You need a common denominator. You already have one. So add 7+9=16. Put 16 over 22. That's your answer without reduction.
When you reduce it, divide it by 2 since its an even number.
16/22=8/11
Answer:
Step-by-step explanation:
The idea of factoring by grouping is that you don't move anything around. You leave the polynomial in descending order of powers of x and group them together in groups of 2.
Then you factor out what is common in each set of parenthesis.
You know if factoring by grouping "works" if what's inside both sets of parenthesis is exactly the same. Both of ours are (x - 12), so grouping "worked". Match the factoring above to one of your answers.
