The point where the two diagonals meet is also the midpoint of both diagonals.

This means that AE = EC . Since we have the value for both segments, we have

AE = EC \implies 2x = x+2 \implies x = 2

Since AC = AE + EC, we have

AE + EC = 2x+x+2 = 3x+2 = 3\cdot 2 + 2 = 6+2 = 8

Order the numbers from least to greatest. <br> 0.5, <br> -2, <br> 1/4, <br> -6.3
adoni [48]

Answer:

Given

Step-by-step explanation:

We have:

0.5

-2.0

-6.3

1/4 = 0.25

So ordering from least to greatest the greater negative integer comes since it is to the far left on the number line to the greater positive integer. Therefore the answer is:-

-6.3, -2, 0.25, 0.5

= -6.3, -2, 1/4, 0.4

Which of these is a correct expansion of (3x -2)(2x^2+5)
labwork [276]

(3x−2)(2x^2+5)

=(3x+−2)(2x^2+5)

=(3x)(2x^2)+(3x)(5)+(−2)(2x^2)+(−2)(5)

=6x^3+15x−4x^2−10

=6x^3−4x^2+15x−10
