Factor this trinomial completely.
zmey [24]
First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)

Each time Henry visits the art museum he pays $15 for parking and $25 for admission.
Flauer [41]

Answer:

A

Step-by-step explanation:

Since it says 'each time ' you would say 15x and 25x. Since that isnt an answer you add them together and get 40x. That eliminates B and C. Next you would do the other side of the equation. He only pays the membership one time but pays for parking every time he goes so it would be 110 and 10x

Geometry help will give brainliest i was wrong
skelet666 [1.2K]
The reason you got it wrong is because you solved for the side a instead of the angle Z, which was what the question asked you to solve for. You can find Z by doing cos Z = 12/35, which will get you cos Z = 0.343, and Z will be equal to about 70º.

Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium. What is her biweekly deduction for th
zzz [600]

Answer:

$73.89

Step-by-step explanation:

We have been given that Kathy Parker's employer pays 65% of the total cost of her $5,489 health insurance premium.

This means Kathy pays 35% of her health insurance premium.

Let us find 35% of $5489.

\text{Amount of health insurance premium paid by Cathy per year}=\frac{35}{100}\times\$5489

\text{Amount of health insurance premium paid by Cathy per year}=0.35\times\$5489

\text{Amount of health insurance premium paid by Cathy per year}=\$1921.15

As we are asked to find Cathy's biweekly deduction for the insurance we will divide amount of premium paid by Cathy by 26 as biweekly is paid 26 times per year.

\text{Cathy's biweekly deduction}=\frac{\$1921.15}{26}

\text{Cathy's biweekly deduction}=\$73.89

Therefore, Cathy's biweekly deduction for the insurance is $73.89.
