The simplified expression of (2x+1)/(x²-3) is 2x/(x²-3) + 1/(x²-3)
<h3>How to simplify the expression?</h3>
The expression is given as:
(2x+1)/(x²-3)
The above expression is a fraction and the numerator has 2 terms
For a fraction
A + B)/x
The fraction can be split as
A/x + B/x
Using the above as a guide, we have:
(2x+1)/(x²-3) = 2x/(x²-3) + 1/(x²-3)
Hence, the simplified expression of (2x+1)/(x²-3) is 2x/(x²-3) + 1/(x²-3)

Answer/Step-by-step explanation:
m<MAH = 90° (linear pair. It is also supplementary to m<MAK = 90°)
m<MAL + m<HAL = m<MAH
Which is:
(9x + 1) + (x + 9) = 90°
Solve for x
9x + 1 + x + 9 = 90
Collect like terms
9x + x + 1 + 9 = 90
10x + 10 = 90
Subtract both sides by 10
10x + 10 - 10 = 90 - 10
10x = 80
Divide both sides by 10
x = 8
Find m<MAL
m<MAL = 9x + 1
Plug in the value of x
m<MAL = 9(8) + 1 = 72 + 1 = 73°
Find m<HAL
m<HAL = x + 9
m<HAL = 8 + 9 = 17°
2x^2-y
=2 (3)^2 -(-2)
=2(9) +2
=18+2
=20

Answer:
Mean = ∑x + standard deviation = 429.21
Step-by-step explanation:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation= ∂ = x-µ / N
∂ = standard deviation
µ= mean
x = size of year
By using formula of standard deviation:
= 70 – 71.45 / 12.53
Approximately equal to 64.21
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21
Answer:8. h(t) = -6 ((t-6) -3.7)^2 + 82.14 +20
9.b) At about 7.4 seconds.
Step-by-step explanation
Yes, on #7 the function is located 3 places to the right and 2.5 up, but that's just counting the tiny squares. If you look at the number and problem, on #8, you can't add +2.5, because the rocket wasn't on a platform 2.5 feet high. Remember that outside the parentheses + means up and - means down. So add + 20(ft). but for question 8, and 9. b), try these answers. please mark brainlest
