Answer:
A. 2x + 9 + 11 over x - 2
Step-by-step explanation:
2x^2+5x-7 over x-2
divide - 2x^2 + 5x - 7 over x - 2 = 2x + 9x - 7 over x - 2
= 2x + 9x - 7 over x - 2
divide - 9x - 7 over x - 2 = 9 + 11 over x - 2
= 2x + 9 + 11 over x - 2

( 7, 2 )
Step-by-step explanation:
I hope this helps you!
Using Pythagorean theorem c^2=a^2 + b^2, we can find the missing side b.
Put values in equation.
18^2 = 8^2 + b^2
324=64+b^2
Subtract 64 from both sides
260= b^2
Take square root.
2√65=b
or
b=16.12
Answer: b=2√65 Radical form. or b=16.12 Decimal form.

Answer:
(c) 162 cm
Step-by-step explanation:
The centroid divides a median into parts with the ratio 1:2, so RL:LD = 1:2. Then RL:RD = 1:(1+2), and RD = 3RL.
RD = 3·54 cm
RD = 162 cm
