Please help me with this question. "line segment AB is drawb on the grid with endpoints A(0,8) and B(6,0). Using only a straightedge and the grid itself divide AB into 4 congruent segments. Explain how you did this and why it works" please explain too

10/4

Step-by-step explanation:

We can use the pythagorem theorem to solve for what is AB

6^2+8^2= c^2

36+64= c^2

100=c^2

c= 10= AB

Since we know that AB is 10 then we can divide it by 4

10/4

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
