Answer:

6)  b. 9 cm

7) a. 0

Using the Pythagorean Theorem,

c² = a² + b²

c² = 40² + 30²

c² = 1600 + 900

c² = 2500

[tex]\sqrt{c^{2} } =\sqrt{2500}[/tex]

c = 50

Then the hypotenuse, or diagonal of rectangle is 50 cm, then...

BD - AC is 50 - 50 = 0

8) c. 50 cm

Explanation:

The 2 diagonals of a rectangle is congruent or have the equal measure of length.

9) d. 9 cm

Explanation:

The 2 diagonals of a rectangle is congruent or have the equal measure of length.  

10) d. 6

Explanation: Both diagonals of a rectangle is congruent.

So, [tex]\overline{MT}\cong\overline{AH}\\[/tex].

[tex]5(x-4) = 2(x-1)\\5x - 20 = 2x - 2\\5x - 2x = 20 - 2\\3x = 18\\x = 6[/tex]
