Answer:
3
Step-by-step explanation:
the answer is x=3 because 4x3 = 12 + 1 = 13. there's your answer. please mark me brainliest!!!
The square root of 48 is the only irrational number in that group.
I think it's 3
It should be 3 because if you have a base of 6 then your height must be 3 to get 18.
Answer:
{-2,10}
Step-by-step explanation:
x^2 - 8x = 20
Take the coefficient of x
-8
Divide by 2
-8/2 =-4
Square it
(-4)^2 =16
Add this to each side
x^2 - 8x+16 = 20+16
x^2 - 8x+16 = 36
The left hand side becomes( x + (-8/2) )^2
(x - 4)^2 = 36
Take the square root of each side
sqrt((x - 4)^2) =±sqrt( 36)
x-4 = ±6
Add 4 to each side
x-4+4 = 4±6
x = 4±6
x = 4+6 x = 4-6
x = 10 x = -2
