Answer:
1 + sin2x
Step-by-step explanation:
Given
(sinx + cosx)² ← expand using FOIL
= sin²x + 2sinxcosx + cos²x
[ sin²x + cos²x = 1 and sin2x = 2sinxcosx ]
= 1 + sin2x
There are 12 m&m.
Because there are 6 skittles to every 4 m&m
There are 18 skittles.
So there must be 12 skittles
Since the coefficients of the <span>x2</span>-term have to be equal on both sides of the equation, <span><span>−<span>8a</span></span>=24</span>, or <span>a=<span>−3</span></span>.
