Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.75x+3=6(x−3)
0.75x+3=(6)(x)+(6)(−3)(Distribute)
0.75x+3=6x+−18
0.75x+3=6x−18
Step 2: Subtract 6x from both sides.
0.75x+3−6x=6x−18−6x
−5.25x+3=−18
Step 3: Subtract 3 from both sides.
−5.25x+3−3=−18−3
−5.25x=−21
Step 4: Divide both sides by -5.25.
−5.25x/-5.25 = -21/-5.25
Answer: x=4
Answer:
18x⁴ - 30x³ + 66x² - 40x + 56
Step-by-step explanation:
1) Distribute
- (6x² + 8) (3x² - 5x + 7)
- 6(3x² - 5x + 7) x² + 8(3x² - 5x + 7)
2) Distribute
- 6(3x² - 5x + 7) x² + 8(3x² - 5x + 7)
- 18x⁴ - 30x³ + 42x² + 8(3x² - 5x + 7)
3) Distribute
- 18x⁴ - 30x³ + 42x² + 8(3x² - 5x + 7)
- 18x⁴ - 30x³ + 42x² + 24x² - 40x + 56
4) Combine like terms
- 18x⁴ - 30x³ + 42x² + 24x² - 40x + 56
- 18x⁴ - 30x³ + 66x² - 40x + 56
