Answer: 16x - 30

Step-by-step explanation:

Determine values of L and W

We know that the perimeter can be found by the equation p = 2L + 2W where L is the length and W is the width

L = 3x-4

W = 5x-11

Plug in the values of L and W into the equation and solve

p = 2L + 2W

p = 2(3x - 4) + 2(5x - 11)

p = 6x - 8 + 10x - 22

p = 16x - 30

Answer:

(16x - 30) units

Step-by-step explanation:

Perimeter = 2[length + width]

= 2[3x-4 + 5x-11]

= 2[8x - 15]

= 16x - 30

Looking for right triangle side a is 1 inch long,and side b is 2 inches long. What is the length of side c?
Sergeeva-Olga [200]

Answer:

\sqrt{5}

Step-by-step explanation:

a^{2} + b^{2} = c^{2}

In this situation a = 1, b = 2

1^{2} + 2^{2}  = c^{2}

1 + 4 = c^{2}

5 = c^{2}

c = \sqrt{5}

This is an important mathematical theorem to know. It's called the Pythagorean Theorem.
