Answer 1

Step-by-step explanation:

i) (5a+3b)+(a−2b)+(3a+5b)=a(5+1+3)+b(3−2+5)

ii) FIND lest common multiplier of 8x - 3y + 7z, -4x + 5y- 4z, -x - y - 22, answer = (-4x+5y-4z) (x-y-22) (8x-3y+7z)

iii)Group like terms

= 3b7c

c-2b-b105c+12c-1515.

Add similar elements: -2b-b= -3b

-3b'c-3b+105c+12c-1515

Add similar elements: 105c+ 12c 117c

-3b¹c-3b+117c-1515

iv) Find Least Common Multiplier of a-3b+3.2a-5-3c, 6c-15+6b.

Factor= 6c-15+ 6b: 3(2c-5+2b)

(2a-5-3c) (2c-5+2b) 3(a-3b+3).

vi) answer is in the picture
