Answer:
A) 8x - 4 || B) 6x + 29
Step-by-step explanation:
A) -2x + 5 + 10x - 9
→ -2x+10x+5-9
→ -2x+10x-4
→ 8x - 4
B) 3(x + 7) + 2(-x + 4) + 5x
→ 3x + 21 - 2x + 8 + 5x
→ 6x + 29
Answer:
A) 8x - 4
B) 6x + 29
Step-by-step explanation:
A) -2x + 5 + 10x - 9 : given
= (10x - 2x) + (5 - 9) : put like terms together
= 8x - 4 : group
B) 3(x + 7) + 2(-x + 4) + 5x : given
= 3x + 21 - 2x + 8 + 5x : expand
= (3x - 2x + 5x) + (21 + 8) : put like terms together
= 6x + 29 : group
Thanks! Have a great day studying!
