Answer:
C: x = -2, 0, and 6
Step-by-step explanation:
First set the equation equal to zero
0 = x³ - 4x² - 12x
now factor out the GCF, which is 'x'
0 = x(x² - 4x - 12)
Now factor completely...
0 = x(x - 6)(x + 2)
So
x = 0
and
x - 6 = 0 becomes x = 6 (add 6 to both sides)
and
x + 2 = 0 becomes x = -2 (subtract 2 from both sides)
So our solutions are
x = -2, 0, and 6
Writing? any ways if 3 miles is 1/4 of the total path then there is 3/4 remaining and we know that 1/4 is 3 miles so how many times does one fit into the denominator(4) it fits 4 times so muptily 3 by4 and you have your answer(12)
Answer:
x=4
Step-by-step explanation:
13-4x=1-x
13=1-x+4x
13=1+3x
12=3x
4=x
x=4
Answer:
The diagonal is 421.
Step-by-step explanation:
This is a difficult question. To find the diagonal, you need to find the base and the height of the square. After that, you need to make it a triangle, by using this equation;
(A being area, B being base, and H being height) then find the length of the hypotenuse of the triangle, which I will do for you.
The B and H = 416. Plug it into the equation now;
Now that you have done that, we know that the area of our new triangle is 86,528.
The diagonal is: ![421](https://tex.z-dn.net/?f=421)
