All you have to do is add 500+100=600. This is easy
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

Answer: x=7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−(12+4x)=−40
−4x+−12=−40(Distribute)
−4x−12=−40
Step 2: Add 12 to both sides.
−4x−12+12=−40+12
−4x=−28
Step 3: Divide both sides by -4.
−4x
−4
=
−28
−4
B is 90° and c is 59°
Add those and you get 149. Subtract 180 from 149 and get 31. D is 31, c is 59, so cd is 90.
