Answer:
2x^2 +4x +4
Step-by-step explanation:
5x ^2 - 3x + 8 - (3x ^2 -7x + 4)
Distribute the minus sign
5x ^2 - 3x + 8 - 3x ^2 +7x - 4
I like to put them vertically
5x ^2 - 3x + 8
- 3x ^2 +7x - 4
-----------------------
2x^2 +4x +4
540 is the answer because you multiply 3 times 10 times 18 or whatever order you want and you'll get 540 so that's your answer
-3-5=2
2y-7y=-5y
2-5y is the answer
The solution to the problem is as follows:
arc sin (sin 3pi) = theta
<span>where theta is the angle ur looking for </span>
<span>so that becomes </span>
<span>sin (theta) = sin 3pi </span>
<span>sin (theta) = 0 </span>
<span>theta = 0, pi
</span>
