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)
All the angles added up = 360°
46 + 4x - 2 + 9x + 6 + 8x - 5 = 360
21x + 45 = 360
21x = 315
x = 15
Let me know if you have questions.
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
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.
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.
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.
Therefore, Cathy's biweekly deduction for the insurance is $73.89.
