240 halves is equal to 120 wholes
The answer is 6*2-6. I hope this helps u
Triangles add up to 180. So add up the two angles given, and subtract that from 180. That will be x!
= 7√(2x) + 2x
or
= 2x + 7√(2x)
answer is A. 2x + 7√(2x)
You put the values of x into the equation to work out y, so the y column would be -5, -1, 3, 7 (for question 6)
For question 7, the y column would be 2,2,0,-2
Use these values to draw the graphs :)
