What is (2x-3) squared?

Answers

Answer 1

Answer:

(2x - 3)² (squared) simplifies to 4x² - 12x + 9.

The Breakdown

(2x - 3)² = (2x - 3) × (2x - 3)

Using the FOIL method, which stands for First, Outer, Inner, Last, you multiply the terms as follows

First: (2x) × (2x) = 4x²

Outer: (2x) × (-3) = -6x

Inner: (-3) × (2x) = -6x

Last: (-3) × (-3) = 9

Collect the like term

4x² - 6x - 6x + 9

4x² - 12x + 9

(2x -3)²= 4x² - 12x + 9.

The area of the first one would be the area of the rectangle minus the area of the circle, so 18*8 - (pi*3*3). That's equal to around 115.7257 inches squared.

The area of the second one would be the area of the triangle plus the area of the semicircle, so [(4*5)/2]*[(pi*2*2)/2]. That would be 20pi, or around 62.8319 ft squared

What are the properties of Triangle?

The properties of the triangle are:

1. The sum of all the angles of a triangle (of all types) is equal to 180°.

2. The sum of the length of the two sides of a triangle is greater than the length of the third side.

3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

The sum of the interior angles in a triangle is 180 degrees. Therefore, we can find the measure of angle O by subtracting the measures of angles N and P from 180 degrees:

m∠O = 180° - m∠N - m∠P

We are given that m∠N = 137 degrees and m∠P = 22 degrees, so substituting these values, we get:

m∠O = 180° - 137° - 22°

m∠O = 21°

Therefore, the measure of angle O is 21 degrees.

Complete question:

in a triangle npo If m∠n = 137 and m∠P = 22, what is m∠O?

so than this is a triangle so we know that the sum of measure of angles of a triangle is equal 180 degrees
- in this case m<O = 180 -(137+22) = 180 -159 = 21

m<O = 21 degrees

What percent of 84 is 9?

Answers

If you would like to know what percent of 84 is 9, you can calculate this using the following steps:

x% of 84 is 9
x% * 84 = 9
x/100 * 84 = 9
x/100 = 9 / 84
x = 9/84 * 100
x = 10.71

The correct result would be 10.71%.

The percentage of the number 84 which equals 9 is 75/7 percent.

How to determine a percentage?

Given the parameter:

"9 is what percent of 84"

To find what percent of 84 is 9, you can use the following formula:

Percent = (Part / Whole) × 100

Where:

Part = 9 (the smaller value you want to find the percentage of)

Whole = 84 (the larger value)

Now, plug in the values:

Percent = (9 / 84) × 100%

Simplifying we get:

Percent = (9 / 21) × 25%

Percent = (75/7)%

Therefore, 9 is 75/7 percent of 84.

One day at St. Philip's High School, 1/2 of the pupils walked to school, 1/5 of the pupils came to school by bus, and the remaining 57 pupils came by car.What fraction came to school by car?

Answers

The first thing to do is the make the denominators of the fractions the same.

5/10 of the pupils walked to school and 2/10 of the pupils came to school by bus.
5/10 + 2/10 = 7/10.
10/10 - 7/10 = 3/10.

3/10 of the pupils came to school by car.
