Step-by-step explanation:
area of rectangle=length×breadth=(2x+3)(3x+7)
=6x²+9x+14x+21=6x²+23x+21
Answer: Mean Score = 50 Range = 31
Step-by-step explanation:
58+76+40+35+46+45+0+100=400
400/8=50
Range = subtract smallest number from largest number
54 - 23 = 31
Answer:
1) 40 degrees
2) 140 degrees
3) 110 degrees
4) 70 degrees
5) 70 degrees
Explanation:
Use the curved protractor they have created you, and count every dash as 10 degrees. Keep in mind that the whole thing equals 180 degrees, and half would equal 90 degrees. Some call it a right angle.

It would be (6,9) from the given end point to the given middle point it is a 7 point difference, so we add 7 to the y value to get the other endpoint, hope it helps!
1. HI Because two parallel lines have to be on the same plane and never intersect.
2. Skew means the never intersect and they aren't on the same plane so it is GK and DH
3. Angle 3 corresponds because it is the bottom left and 7 is the bottom left.
4. 3 and 5 are same-side interior because they are both on the left side and both are inside.
Hope this helps!
