It is 22 cuz 5 * 2 is 10 and 10 * 2 IS 20 + 2=22
Answer:
See below ↓
Step-by-step explanation:
14.
- Between two lines m ║ n, the ∦ cuts through them forming two angles
- As it forms a line, the sum of the angles is 180°
- 3x + 47 + x + 7 = 180
- 4x + 54 = 180
- 4x = 126
- x = 126/4 = 63/2 = 31.5
15.
- Alternate exterior angles on a transversal are equal
- 5x = 2x + 78
- 3x = 78
- x = 26
Are you in kindergarten
divide 10x^3 by 5x to get 2x^2 and then divide -25x by 5x to get -5
Answer is 2x^2-5
Choice #1
×= 10 and ×= -14
Find x by simplifying both sides of the equation then isolate the variable.
