Answer:
3x^2-9=0
Step-by-step explanation:
√3 does not equal a whole number.
Y +6 =(1/2)(x+4)
y +6 = 1/2 x +2
y=1/2 x - 4
or 1/2 x -y = 4
Answer:The answer for the first one is log2(.25)=-2
The answer for the second one is 8^3=512
Step-by-step explanation:
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
Answer: 20
Step-by-step explanation:
First is 6 x 3 which is 18 then take away 5 so it would be 13 and + 21/3 is basically a seven so its <u>20</u>
