Um? ? #8 send ! write an algebraic expression for two numbers with a sum of -10. let one of the numbers be represented by x. if one number is represented by x m, how would the other number be represented?

Here is your answer.

Step-by-step explanation:

Sum: -10

Expression:

X = 2

m = -5

(multiplying X and M)

XM = -10 (X times M = -10) (-10 = negative 10)

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
