2/3 of 6 parts would be:
2/3=x/6
X=4
So shade 4 of the 6 parts.
I would say none
because each one equals to 24 students, when it says there are 24 students in each are class. so you would need to do 24 * 5 to get the amount of students.
You have to use sin/cos/tan values
32. For every one salad it was 8 steaks, so if they sold 4 steaks, just multiply 4 by 8, where 8 represents the number of salads for every steak. The answer would be 32. Correct me if I'm wrong but that my answer.
This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !
You're totally correct, as far you went. x² + 2x does = -1
Now add ' 1 ' to each side: x² + 2x + 1 = 0
Can you factor that quadratic ?
Can you mash it through the quadratic formula ?
Actually, it's the simplest possible perfect square.
x² + 2x + 1 = (x + 1)²
So the solutions of x² + 2x + 1 = 0 are both x = -1 .
Don't say anything.
I know it's embarrassing.
