A•B=C
A•B=-21
Find factors of 21 ( it doesn't matter that it's negative ) that at up to be 4
It's 7and 3
Then put x^2+7x+3x-21 and then factor by grouping
Do the same steps for #2
Answer: B. $32.50
Step-by-step explanation:
The premiums listed in brackets are for every $25,000 of coverage.
Mateo wants a $100,000 coverage so we need to divide this by $25,000 to see how much more he will have to pay:
= 100,000 / 25,000
= 4
Mateo will have to pay 4 times the $5.50 for himself:
= 4 * 5.50
= $22.00
For his spouse who requires $75,000, he will have to pay:
= 75,000 / 25,000
= 3
= 3 * 3.50
= $10.50
Total Mateo is to pay for both his spouse and himself is:
= 22 + 10.5
= $32.50
Answer: -6/11
-4x - 2(8x + 1) = -(-2x - 10) Distributive Property
-4x - 16x - 2 = 2x + 10 Combine like terms
-20x - 2 = 2x + 10 Subtract 2x from both sides
-22x - 2 = 10 Add 2 to both sides
-22x = 12 Divide by -22 for both sides
x = -6/11 Answer!

Answer: Choice A</h3>
This is because we're adding -6 to each term, i.e. subtracting 6 from each term, to get the next term
- -2+(-6) = -8
- -8+(-6) = -14
- -14+(-6) = -20
- -20+(-6) = -26
and so on. The gap between adjacent terms is the same width. We say that the common difference is d = -6.
I got 6 units^2. So the answer is the second choice. ab/2 = 3*4/2 = 6.
