Answer:
-cos^4(x)
Step-by-step explanation:
Step 1: Use the Pythagorean identity : 1=cos^2(x) + sin^2(x)
1-sin^2(x) = cos^2(x)
-1+sin^2(x) = -cos^2(x)
cos^2(x) (-cos^2(x))
Step 2: Factor out common terms cos^2(x)
cos^2(x) (sin^2(x)-1)
Ans: -cos^4(x)

Step-by-step explanation:
Hey there!
Answer = -14
Explanation:
Let's solve your equation step-by-step.
x + 2 = -12
Subtract 2 from both sides:
x + 2 - 2 = -12 - 2
x = -14
So therefore, that is how you found your answer: x = -14
What I would do is break up into part. First do 10*10*10 which is 1,000. Then add 56 and 50 which is 106. after you do that and get 1,106 divded it by 25 which is 42.54. Hope I helped.
