the correct x intercept would be 1 and -4 i believe!
16: 10(-9) +4 = -90 +4 = -86
17. 7^2 - 7 = 49-7 = 42
18. -9^2 - -9 = 81+9 = 90
19. 10(5) +4 = 54, 3*54 = 162
20. 3*5 = 15, 10(15) +4 = 154
Answer:
1)250

3)11664
Step-by-step explanation:
The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube. We have 96 = 6a2 → a2 = 16, so that's the area of one face of the cube.
Hope it helped you if yes so please make me the brainist
