The answer is 94 just subtract 21 from 115 & that’s equals 94.
Answer:
= cos4x
Explanation:
cosAcosB = [cos(A-B)+cos(A+B)]
Given: 2cos(2x)cos(2x)
= 2[cos(2x-2x)+cos(2x+2x)]
= 2cos4x^2
Answer:
The remainder = 13.
Step-by-step explanation:
By the Remainder Theorem the remainder when the function is divided by
x - 1 is f(1).
f(1) = 4(1)^3 + 4(1)^2 + 2(1) + 3
= 4 + 4 + 2 + 3
= 13.
So x - 1 is not a factor of f(x).
If it was a factor the remainder would be 0.
You need to set up a fraction. You can use red/blue which would be 5/7. Then, create the second ratio which would be 8/12. And there you will find your answer, which this answer also works for your answering wether you get yes or no.
