Answer:
(3x^2-5x-5)/(x^2+x) <--- answer
Step-by-step explanation:
3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]
= (3x^2 - 5x - 5)/(x^2 + x)
Answer: B
Step-by-step explanation:
<u>Given:</u>
36=<1.02D-31.2<=41
<u>Solve the compound inequality for D:</u>
36+31.2<=1.02D<=41+31.2
67.2<=1.02D<=72.2
65.9<=D<=70.8
Therefore, option (b) is correct answer
No real way to solve it, with the knoledge of the perfect squares (1,4,9,16,25,49 ect) you can do the simple ones but more complicated ones require a calculator to solve it in decimal form
TIP:
If you need to find the graph for an equation, simply plug the equation into desmos graphing calculator! :)
We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)
To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c
Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)
