11 feet = 132 inches
The boards are x, x and (x-3) inches long.
x + x + x -3 = 132
3x = 135
x = 45
The boards are 45 inches, 45 inches and 42 inches long.
Answer:
9 sq units
Step-by-step explanation:
1.5+1.5+4.5+1.5 = 9
Answer:
C
Step-by-step explanation:
Angle in a triangle add up to 180
since this is an isosceles triangle two angles are the same
180-(47+47)=86
Opposite angles are equal
Angles around a point add up to 360
360-(86+86)=188
188/2=94
94 degrees

The first three steps for solving the quadratic equation by completing the square are as follows;
1. 
2. 
3. 
Given
The quadratic equation given as 9x^2 + 54x = 7.
<h3>Quadratic equation;</h3>
The highest power of the degree is 2 is known as a quadratic equation.
To solve using the completing the square method.
The first three steps for solving the quadratic equation by completing the square are given below.
1. Write the equation in a way that the constants are on the right side while the terms with x are on the left.

2. Make sure that the coefficient of the x^2 term is 1.

3. Adding a term to both sides that will complete the square on the left side.
This is done by dividing the coefficient of the x term by 2 and squaring it.
The same amount should be added to the right side to balance the equation.

Answer: 2w = 16
Step-by-step explanation:
From the question, we are informed that Luis walked for 16 minutes while Natalie walked for w minutes and that Luis walked twice as long as Natalie.
The number of minutes that Natalie walk will be:
2 × w = 16
2w = 16
Solving further will be:
2w = 16
w = 16/2
w = 8
Natalie walked for 8 minutes
