Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Given
sin²x + 7cosx + 17
=1 - cos²x + 7cosx + 17
= - cos²x + 7cosx + 18 ← factor out - 1 from each term
= - (cos²x - 7cosx - 18)
Consider the factors of the constant term (- 18) which sum to give the coefficient of the cosx term (- 7)
The factors are - 9 and + 2, thus
= - (cosx - 9)(cosx + 2) ← in factored form

Answer:
$ 246
Step-by-step explanation:
3% of 3,200 is 96
so 96 + 450 = 246
45*6 = 270
280-270 = 10
45 can go into 280 , only 6 times, and their is a remainder of 10.
well, I think the whole group thing is ment to distract you. Math problems can be evil like that. If she has 200 pencils. and 137 ove them a sharp, you have to subtract 137 from 200. 200-137=23 :3 she has 23 unshapened pencils.
