Answer:
x^2 + 7x- 3/x - 3/x^2 -16
Step-by-step explanation:
Key: ( ^ ) means exponent
= x^2 + 2x- 3/x -2x^2 + 5x- 3/x^2 -16
= x^2 - 2x^2 + 2x+5x - 3/x- 3/x^2 -16
= x^2 - 2x^2 = -x^2
= -x^2 + 2x + 5x- 3/x- 3/x^2-16
As you see you add 2x and the 5x and got 7x
= Answer : <u>x^2 + 7x- 3/x - 3/x^2 -16</u>
The answer is 20s+10h=500
The reason is because 20 times 20=400 and then 10 times 10= 100 then you add those together and get $500
1.5kg = £2.13
1kg = $1.42
1000gm = $1.42
0.5kg = $0.71
500gm = $0.71
1. 42+ 0.71 = £2.13 = 1.5kg = 1500gm
9.5
Divide 60 by both sides
