Answer:
x=40
Step-by-step explanation:
30x-215=985
Add 215 to each side
30x -215+215 =985+215
30x = 2100
Divide each side by 30
30x/30 = 1200/30
x=40
8/7 each side of the expression both go up by 1
Answer:
2x⁴ + 4x³ + x² + 8x - 6
Step-by-step explanation:
(2x² + 4x - 3)(x² + 2)
2(x² + 2) · x² + 4x(x² + 2) - 3(x² + 2)
2x⁴ + 4x² + 4x(x² + 2) - 3(x² + 2)
2x⁴ + 4x² + 4x³ + 8x - 3x² - 6
2x⁴ + x² + 4x³ + 8x - 6
2x⁴ + 4x³ + x² + 8x - 6
