What is the perimeter of this figure?

krok68 [10]

Answer:

D) 44 inches

Step-by-step explanation:

Isosceles trapezoids have equal legs, which is why they are called isosceles.

Squares have equal side lengths are around, so you know that the missing side lengths to this figure are 5 in, 10 in, and 10 inches.

Add all of the given values together.

5 in + 4 in + 10 in = 19

Add all of the "unknown" values together.

5 in + 10 in + 10 in = 25

Add these two values together.

19 in + 25 in = 44 inches

This answer corresponds to answer choice D.

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Step-by-step explanation:

Step 1: Define

4x² + 9x - 1 = 0

Step 2: Define variables

a = 4

b = 9

c = -1

Step 3: Find roots

Substitute: $x=\frac{-9\pm\sqrt{9^2-4(4)(-1)} }{2(4)}$
Exponents: $x=\frac{-9\pm\sqrt{81-4(4)(-1)} }{2(4)}$
Multiply: $x=\frac{-9\pm\sqrt{81-16} }{8}$
Subtract: $x=\frac{-9\pm\sqrt{65} }{8}$
