Answer:

Step 2, he didn't add the values he completed the square with to both sides.

Step-by-step explanation:

When you complete the square, you need to add the values to both sides, not just one.

So when Homer added 49 + 1 or 50 to the left side of the equation, he should've also added 50 to the right side of the equation.

Hence, the equation would now be :

(x-7)^2 + (y+1)^2 = 75

Travka [436]

Answer:

Population parameter

Step-by-step explanation:

Since the average price of a whole town at a new dealership is described. A random sample from a town was not isolated for study. In fact the entire statistics of the town was considered in the mean price of a car. Hence, the average price given in our case will be a population parameter.

the area of a rectangular window is 6216 cm^2. if the length of the window is 84 cm, what is it's width?

Rus_ich [418]

Answer:

<h3>The answer is 74 cm</h3>

Step-by-step explanation:

The area of a rectangle = length × width

Since we are finding the width

We have

$width = \frac{area}{length} \\$

From the question

area = 6216 cm²

length = 84 cm

The width is

$width = \frac{6216}{84} \\$

We have the final answer as

ALGEBRA determine the angle measure in the polygon.a. 30°, 150°, 30°, 150°b. 30°,30°,30°,30°c. 45°,225°,45°,255°D. 15°,75°,15°,7

Veseljchak [2.6K]

We know that consecutive angles in a parallelogram are supplementary, as they are consecutive interior angles between parallel lines.

Then, if we add the measure of x° and the measure of 5x° we get 180°. Then, we can write this expression and solve for x:

$\begin{gathered} x+5x=180 \\ 6x=180 \\ x=\frac{180}{6} \\ x=30 \end{gathered}$

Then, the angle x has a measure of 30° and the angle 5x has a measure of 5*30=150°.

Answer: a. 30°, 150°, 30°, 150°
