Answer:

16

Step-by-step explanation:

The triangle AEC is a right triangle and 2 sides are already filled in.

The hypotenuse is 10 and one side is 6.

So, this is a 3-4-5 right triangle.

Thus, the remaining side EC is 8.

Since EC is congruent to ED, then segment CD is 8+8=16

Answer:

Answers in Explanation

Step-by-step explanation:

First Question:

\sqrt{100} + [18 ÷ 3 x 4 - 15] - (60 - 7^2 - 1)

\sqrt{100} + [24 - 15]  - (60 - 49 - 1)

\sqrt{100} + 9 - 10

10 + 9 - 10

<u>Answer = 9</u>

Second Question:

5x + 2x = 7x

5x^2 + 3x^2 = 8x^2

2x + 3x - x = 4x

2x + 3y + x + y = 3x + 4y

9x - 6x = 3x

-7y + 3x + 4x + 3y = 7x - 4y

-7x^2 + 2x^2 + 9x^2 = 8x^2

(3x^2 + 5x + 4) - (-1 + x^2) = 2x^2 + 5x + 5

(3 + 2x - x^2) + (x^2 + 8x + 5) = 10x + 8

(3x - 4) - (5x + 2) = -2x - 6

(2x^2 + 5x + 3) - (x^2 - 2x + 3) = x^2 + 7x

(3x^2 + 2x - 5) - (2x^2 - x - 4) = x^2 + 3x - 1

Third Question:

17x + 2y

(5x + 12y) + (3x + y) = 8x + 13y

17x - 8x = 9x

2y - 13y = -11y

Answer: 9x - 11y
