Step-by-step explanation:

1) (2x^{2} - 9x + 4) + (3x^{2} + 2x - 3)

= 2x^{2} - 9x + 4 + 3x^{2} + 2x - 3

= 5x^{2} - 7x - 1

2) x^{2} - 4x - 3 + x^{2} -2x - 3

The annual health insurance premium for Ms Everett is $12,304. her employer pays 70% of the premium and deducts the remainder fr
Gekata [30.6K]
Answer: See each one below:

1) Since she is paying for 30% of the cost, we multiply it by 0.3. Then, since it is over the whole year, we divide it by 12.

12304 * 0.3 / 12 = 307.6 B

2)  First, we subtract the cost of the 50 deductible, then multiply the amound by 0.2 because he has to pay 20% of the balance.
1060 - 50 = 1010 x 0.2 = 202 A

3)  First, we find the total cost of the visits. Mattie has to pay for 40% so times it by 0.4. Then, don't forget to add in the cost of 12 co-pays of $15 each.
3660 * 0.4 = 1464 + 15(12) = 1664 B

A triangle has an area of 9m2 and a base of 6m. how do I find the height of this triangle?
KonstantinChe [14]
You know the triangle has a base of 6 meters, and that the formula to find the area of a triangle is 1/2bh or one-half of the base times the height. So, you would plug in 9 meters squared=one half of six times h, or 9m^2=1/2(6)*(h). In simplifying this, you would get 3h=9m^2. Divide both sides by three and get h=3. Hope this helps, and if you need any further explanations, please let me know!
