An expression is shown below: the square root of 18 plus the square root of 2 Which statement is true about the expression? √18 + √2 It is rational and equal to 4 times the square root of 2. It is irrational and equal to 4 times the square root of 2. It is rational and equal to 3 times the square root of 2. It is irrational and equal to 3 times the square root of 2.

can you give me more detail on this! ?

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
