Answer:
Four consecutive integers are represented by: x, x+1, x+2, x+3 Their sum is 4x+6 4x+6 = 90
Step-by-step explanation:
hope it helps :)
There were 14 bees in one place and 17 in the other each have their own square and in total there is 31
2(4z−2) = 44
Simplify both sides of the equation.
Distribute:
(2)(4z)+(2)(−2) = 44
8z + −4 = 44
8z − 4 = 44
Add 4 to both sides.
8z − 4 + 4 = 44 + 4
8z = 48
Divide both sides by 8
8z/8 48/8
z = 6

This is what you're looking for if I'm not mistaken
sin²x + cos²x = 1
So:
sin²x = 1 - cos²x
∴ sin²x * cos²x = (1 - cos²x) * cos²x
= cos²x.(1 - cos²x)
(= cos²x - cos⁴x)
