Answer:
A) -1
Step-by-step explanation:

We can rewrite 2√5 - 3 as -(3 + 2√5)
Therefore,

We can cancel out 3 + 2√5 both in the numerator and the denominator. So we get
= 1/-1
= -1
Answer : A) -1
Thank you.
Answer:
50
Step-by-step explanation:
since the Pythagorean theorem is
√
b is the bottom line (48)
a is the right line (14)
c is the top line (c)
plug that in
√
then do the exponets
= 14 * 14 = 196
= 48 * 48 = 2304
then add them together
196 + 2304 = 2500
√2500
the sqrt of 2500 is 50 (50 * 50 = 2500)
c = 50
your answer is 50
hope this helps:)
2x + 3x = 100
5x=100
x=100/5
x= 20
Therefore, 2x=2×20=40
3x=3×20=60
Please mark me as brinliest.......
Glad to help you......
