Answer:
b. 4m+5
Step-by-step explanation:
Answer:
x³ + 4x² - 3x - 2
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor
(x - 1)(x² + 5x + 2)
= x(x² + 5x + 2) - 1(x² + 5x + 2) ← distribute both parenthesis
= x³ + 5x² + 2x - x² - 5x - 2 ← collect like terms
= x³ + 4x² - 3x - 2
28. 6x+42-20=6x
42-20=0
42-20 gives you 22
22=0
Statement is false
30. -2x-4=-2x-3-1
-2x-4=-2x-4
Statement is true because both sides are identical
32. 2x+8-5=2x+3
8-5=3
3=3
Statement is true for any value of x
34. 3x+(x+4)=18
3x+x+4=18
4x+4=18
4x=18-4
4x=14 (next divide both sides by 4)
x= 7 over 2
7/2
Step-by-step explanation:
a = 12√3
b = 24
