Answer:
The solution to this question is 11.
Step-by-step explanation:
Given that
√(2x-5) - √(x+6) = 0
√(2x-5) =√(x+6) equation (1)
square of the equation (1)
(√(2x-5))^2 =(√(x+6))^2
we know that √a*√a=(√a)^2=a.So
2x-5=x+6 after square.
2x-x=6+5 exchange value
x=11
Answer:
Well the answer should be (x,y) => (x+2, y-4). So i'm not sure if you misspelled option A because you wrote (x+2, 7-4). If that 7 is supposed to mean y, then the correct answer is A.
Answer:
14.13
Step-by-step explanation:
use the radius, 3 squared
so 3 x 3 = 9
9 x 3.14 = 28.26
28.26 / 2 ( because it is a semicircle) = 14.13
