Answer:

umm, a=3 I believe?

Step-by-step explanation:

4²=16, and 5²=25 so 25-16=9 and the square root of 9 is 3

Answer:

a = 3

Step-by-step explanation:

a^2 + 4^2 = 5^2

Step 1 square all exponents

a^2 + 16 = 25     4*4 = 16 and 5*5 = 25

Step 2 subtract 16 from both sides

a^2 +16 = 25

      -16    -16

a^2 = 9

Step 3 square root both sides

a = 3       square root of 9 is 3

Hope I helped!!

Kite WXYZ is graphed on a coordinate plane. What is the area of the kite?
Misha Larkins [42]

Answer:

14 square units

Step-by-step explanation:

There are several ways we can find the area.  Probably the easiest is to cut the kite in half vertically and find the area of each triangle.  The area of the kite will be double that.

The height of the kite is 7 units, and the width is 4 units.  So each triangle will have a base of 7 and height of 2.

A = 1/2 bh

A = 1/2 (7) (2)

A = 7

The area of the kite is double that, so:

2A = 14

Solve x2 + 12x = –11 by completing the square. Which is the solution set of the equation?
Ann [662]
If you would like to solve the equation x^2 + 12 * x = -11, you can calculate this using the following steps:

x^2 + 12 * x = -11
<span>x^2 + 12 * x + 11 = 0
</span>(x + 1) * (x + 11) = 0
1. x = - 1
2. x = - 11

The correct result would be x = - 1, or x = - 11.

Solve over the set of real numbers for the equation below x-2=√2x-1
Anon25 [30]

The set of real numbers for the equation x – 2 = √(2x – 1) will be 5.

<h3>What is the solution of the equation?</h3>

The solution of the equation means the value of the unknown or variable.

The equation is given below.

x – 2 = √(2x – 1)

Square on both side, then we have

               (x – 2)² = 2x – 1

         x² – 4x + 4 = 2x – 1

         x² – 6x + 5 = 0

   x² – 5x – x + 5 = 0

x(x – 5) – 1(x – 5) = 0

       (x – 5)(x – 1) = 0

                         x = 1, 5

The set of real numbers for the equation x – 2 = √(2x – 1) will be 5.

More about the solution of the equation link is given below.
