Answer:
sin⁴x - sin²x
sin²x(sin²x - 1)
(1 - cos²x)(1 - cos²x - 1)
(1 - cos²x)(-cos²x)
-cos²x + cos⁴x
cos⁴x - cos²x
I think it would be 4.7A - C
4, 4+4 is 8 which is double of 4
This is what I learned:
D = Divide
M = Multiply
S = Subtract
B = Bring down
C= Check
D= Dad
M= Mom
S= Sister
B= Brother
C= Cousin
Hope this helped you! :)
Answer:
C, -4
Step-by-step explanation:
slope=change in y/change in x


multiply both sides by 2/5

simplify the right side. 2/5 × 5 = 2 and 2/5 × 10 = 4


bring y to the other side by adding y on both sides

subtract 6 on both sides

so y is -4
