X^2+16-38=0
find what 2 numbers multiply to get -38 and add to get 16
find factors of 38
2 times 19
there is no way to use common factor so use quadratic formula which is
x=

or x=

ax^2+bx+c=0 subsitte
a=1
b=16
c=-38
subsitute

=

=

=

=

so the answers for x are

and

which are aprox -2.099504938362 and +18.099504938362
so it would be
(x-[-8+√102])(x+[8+√102])=0
Do you mean cube root because the cube root of 24 is 2.88 and other repeating decimals
We have the following general rule for exponents:

then, in this case we have the following:

therefore, the answer is 3
Answer:
Distributive Property
Step-by-step explanation:
Answer choice a is correct because you are distributing 2 to each term in the parentheses. When you multiply 2 to each factor in the parentheses, it simplifies to 2x-2, thus making the new equation 6x+2x-2=30
Answer:
C is correct
Step-by-step explanation:
Comparing the to equation with slope intercept form: 
The second equation has the greatest slope, which is indicating that the line is steeper.
