Answer:
b²+3.5a+8.4b
Step-by-step explanation:
Given the expression
3b^2 + 2(a+5.4b) -2.4b + 1.5a - 2b^2
Expand
3b^2 + 2a+10.8b -2.4b + 1.5a - 2b^2
Collect the like terms
= 3b²-2b²+2a+1.5a+10.8b-2.4b
= b²+3.5a+8.4b
Hence the equivalent expression is b²+3.5a+8.4b
X / 6/7 is 3 2/5. First, concert the numbers to decimals for simplicity sake, and you get x/.857 = 3.4. Multiply both sides by .857 to get x alone and you get x ≈ 2.9143
