Can someone help me with this? I need to find the distance and midpoint

Distance is 9.21954445729 (9) and the midpoint is (-2, 1.5)

Step-by-step explanation:

Pythagorean theorem

Height = 7 and Length = 6

7^2 + 6^2 = c^2

49 + 36 = c^2

85 = c^2

c = 9.21954445729

Botton point is (1, -2)

x: 1 - 3 = -2

y: -2 + 3.5 = 1.5

Midpoint = (-2, 1.5)

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.
