Answer:

Step-by-step explanation:

A) 258 x 8145 + 6 = 2101416

And

258 x 8145 = 2101416

So it is NOT the answer because 258 x 8145 + 6 is not 6times than the value of 258 x 8145

B) 6435 x (75452 + 4) =485559360

And

6435 x 75452 = 485533620

So it is NOT the answer beacuse 6435 x (75452 + 4) is not 4 more than the value of 6435 x 75452

D) 9,035 x (432 − 3) = 3876015

AND

9,035 x 432 = 3903120

So it is NOT the answer because 9,035 x (432 − 3) is not 3 less than the value of 9,035 x 432

THE ANSWER IS C BECAUSE :

7,684 − 4,322 = 3362

AND

2 x (7,684 − 4,322) = 6724

And when we do

6724 ÷ 3 =3362

So 7,684 − 4,322 is half value of 2 x (7,684 − 4,322)

The equation 3x² - 48x + 6856 represents the area of the gym and track together in terms of width.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

A rectangular building for a gym is three times as long as it is wide. Just inside the walls of the building, there is a 6ft rectangular track along the walls of the gym and has an area of 7000ft²

Let x be the width of the rectangle.

As the area of track along the walls of the gym is 7000ft²

(x - 12)(3x - 12) = 7000

After simplifying:

3x² - 48x + 6856 = 0

Thus, the equation 3x² - 48x + 6856 represents the area of the gym and track together in terms of width.

Find the measure of each angle using the triangle sum theorem and exterior angle theorem

Paladinen [302]

(please open my photo for reference as you read, I am a visual learner/explainer so it will make the most sense that way)

So the first thing you want to do is look at the exterior angle 130°. A straight line is 180°, and every Triangle's angular sum is 180°. How I think of it is that every straight line has a mini protractor on either side. It makes it a bit easier to understand.

180 - 130 = 50

You now know that two of the angles are 50°.

You now have two of the measurements for the triangle farthest to the left.

75° and 50°

75 + 50 = 125

180 - 125 = 55

a = 55°

Now that you have all the measurements for the first triangle, let's move onto the next one.

With two measurements for the second triangle, all you need to do is find their sum and subtract that from 180 and you will have the third measurement!

50 + 60 = 110

180 - 110 = 70

b = 70°

Finally, for the last triangle, you already have two of the measurements 60° and 85°.

85 + 60 = 145

180 - 145 = 35

c = 35°

Sorry if this explanation is a bit messy, it's hard to describe certain things without a letter or some kind of name to differentiate between them verbally.

I hope this helps! <3
