Answer:
Step-by-step explanation:
let the slope for the perpendicular to given line : m
you have : m ×2/3 = - 1
2m = - 3
so : m = -3/2
-3/2
Take the reciprocal or flip it, then make it the opposite sign.
d
b
a
c
degree 1 - 5x+5 - d.
degree 2- 3x^2-2x+4- b.
degree 3 - 1/2x^3+8x^2-3- a.
degree 4 - x^4+(x+4)^2- c
Answer: =1

x = 12
Sides of similar figures are proportional, so ...
AB/FE = BC/EC
x/6 = 10/5
x = 6·(10/5) . . . multiply by 6
