Find the value of x so that the shaded region is a gnomon to the white rectangle.
RUDIKE [14]

Based on the shaded region, the value of x which makes this region a gnomon is x = 1.

<h3>What is value of x?</h3>

Based on the dimensions of the side that isn't shaded, and the dimensions of the side that is shaded, the value of x can be found as:

3/ 6 = (1 + 3) / (x + 6 + x)

1/2 =  4 / (6 + 2x)

6 + 2x = 4 / (1/2)

2x = 8 - 6

x = 2/2

x = 1

Can a math equation be like this:
ANTONII [103]

Answer:

  • Yes

Step-by-step explanation:

As per given information there are 18000 CCTV cameras in the area of 783.8 square kilometers

To find the average number of cameras you divide the number by the area.

The average number of CCTV cameras per square kilometer in NYC = 18000/783.8 = 22.9650421026 ≈ 23

It should be rounded up if taking approximate number

Yes you can have as many equal signs as you need and the approximately equal sign in the same equation.

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a&gt;1
Tamiku [17]

Answer:

<h2>4(5x + 6)</h2>

Step-by-step explanation:

5(6x+4)-2(5x-2)\qquad\text{use distributive property}\ a(b+c)=ab+ac\\\\=(5)(6x)+(5)(4)+(-2)(5x)+(-2)(-2)\\\\=30x+20-10x+4\qquad\text{combine like terms}\\\\=(30x-10x)+(20+4)\\\\=20x+24

20x=4\cdot5x\\\\24=4\cdot6\\\\20x+24=4(5x+6)

spin [16.1K]

Answer:

y=-1x+8 \\or\\y=-x+8

Step-by-step explanation:

Okay so we know that line on the triangle DEF that's parallel to the line BC is EF. This because they have the same slope and we can prove that while solving for slope-intercept form.

First we figure out our points for both the lines:

BC:  B=(-2,4)   \\C=(1,1)

EF: E=(4,4)\\F=(6,2)

Now that we have our points we can use the slope formula to prove these two line have the same slope and are therefore parallel to eachother:

\frac{y_1-y_2}{x_1-x_2} = Slope Formula

BC = \frac{4-1}{-2-1} =\frac{3}{-3} =\frac{-3}{3} =-1

EF = \frac{4-2}{4-6} =\frac{2}{-2}=\frac{-2}{2}= -1

So now we proved that both of these lines have a slope of -1. Then we can use the slope intercept formula and one of the points from the line EF to find the y-intercept of the of line EF:

Let's use point = (4,4)

y=4,m=-1,x=4,b=?

y=mx+b\\4=-1(4)+b\\4=-4+b\\(+4) 4=-4+b(+4)\\8=b

We used the formula and found that the y-intercept was (0,8), so now we plug in all of our answers:

y=-1x+8

This is the complete answer but if you wanted to simplify it more you could write it as y=-x+8, cause as long as you make the x negative in the equation it will always be as if you multiplied it by -1.
