Answer:
x<1 is right
Step-by-step explanation:
When you simplify the square root of a number, you are looking for factors of the number that are perfect squares that you can remove from under the radical. For example sq root of 8... it's not a perfect square but factors of 8 include 2 x 4... 4 is a perfect square so we can take it out of the radical by taking it's square root. Now you are left with 2* sq root of 2.
For sq root of 48
48 = 12 x 4
12 = 3x4 so we can say 48 = 3x4x4
so... sq root 48 = sq root 3x4x4
we have two 4's under the radical. Sq root x^2 = x so sq root 4^2 is 4
Pull it out from the radical and we are left with 4 * sq root 3
Answer:
B - 108
Step-by-step explanation:
A regular pentagon is 540 degrees. Divide 540 by 5 (since there are five sides) which equals 108 degrees.
Answer: -4
Step-by-step explanation:
(2x-6×2)(5×2×2)
-24+20
-4
Answer:
all x are the solution
Step-by-step explanation:
x - 4×3 - 4×(-2x) = 3×3x + 3×4
x - 12 + 8x = 9x +12
9x + 12 = 9x + 12
9x = 9x
(0 = 0)
no matter which number we take for x the equation will always be correct
ex. x = 3 : left : 9×3 = 27
right : 9×3 = 27
