Answer:
sqrt(5) + 8
The result is irrational because the sqrt(5) is a non-repeating, non terminating decimal that cannot be written as a fraction.

Step-by-step explanation:
sqrt(5) + 2sqrt(16)
sqrt(5) + 2(4)
sqrt(5) + 8
Answer: 2x^3+4x+4 would be the answer.
Step-by-step explanation: x^2 can only be combines with another variable with the same exponent. Then you just multiply the whole equation by 2. Hope this helps!
First you have to write the equation...(x+7)5=30
then solve; so, x= -1
Answer:
B
Hope you get it right! :)
Step-by-step explanation:
We know that the angle of a straight line is 180°.
So we know that (5x-5) + (2x+10) = 180
We will then solve for x
5x - 5 + 2x + 10 = 180
7x + 5 = 180
7x = 175
x = 25 (just an explanation of how we get 25)
To get angle 1, we will then plug in x=25 into the first equation to get
5(25)-5 = 125-5 = 120°
