For what values of x are the following expressions equal to each other.
the binomials x^2 - 6x and 5x-18

Answers

Answer:

x = 9, 2

Step-by-step explanation:

Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

The values of x that make the expressions x² - 6x and 5x - 18 equal to each other are x = 2 and x = 9.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

To find the values of x that make the expressions  x²  - 6x and 5x - 18 equal to each other

We have to set them equal to each other and solve for x:

x² - 6x = 5x - 18

x²  - 11x + 18 = 0

Next, we can factor this quadratic equation:

(x - 2)(x - 9) = 0

Now we can use the zero product property and set each factor equal to zero:

x - 2 = 0 or x - 9 = 0

Solving for x, we get:

x = 2 or x = 9

Therefore, the values of x that make the expressions x² - 6x and 5x - 18 equal to each other are x = 2 and x = 9.

The area of the shaded portion is 106 square m. I got this number by finding the area of the WHOLE figure (120 because that’s what 10 times 12 equals) then I subtracted that by the area of the white portion (14 because 7x2 equals that). Then I just subtract 14 from 120 and get 106. Hope this helps

OMG PLZ HELP ME! it is due tomorrow.....!

Answers

Step-by-step explanation:

Dilations do not change your angles, so although the length does change, your angles will not. So for your answer, the angles will be the exact same.

For the length, all you have to do is multiply each side by 5/2.

8: Multiplied by 5/2 is 20

9: Multiplied by 5/2 is 22.5

7: Multiplied by 5/2 is 17.5

The lengths are getting larger because they're being dilated by a number greater than 1.

I hope this helps :)

Answer:

Answers bellow hope I helped

Step-by-step explanation:

A)Each angle is the SAME becouse we are just making the triangle larger but the angles stay the same so:

Z' = 50°

X' = 70°

Y' = 60°

B)You have to multiply each of the sides by your scale factor so:

Side X'Y' = 7 x 5/2= 17.5

Side X'Z' = 8 x 5/2 = 20

Side Z'Y' = 9 x 5/2 = 22.5

A pizza parlor sells pizza in two sizes, a 16 inch pizza or a 10inch pizza. Which is more pizza, half of the 16-inch pizza or the entire inch pizza?

Topic: arc length and sector area

Answers

Answer:

Therefore the second pizza of 10inch is More

Y>X

Step-by-step explanation:

From the question we are told that:

Diameter of pizzas

Pizza one [tex]D_1=16[/tex]

Pizza two [tex]D_2=10[/tex]

Generally the equation for amount of half of pizza one X is mathematically given by

[tex]X=\frac{1}{2}\pi r^2[/tex]

[tex]X=\frac{1}{2}\pi 8^2[/tex]

[tex]X=100.53inch^2[/tex]

Generally the equation for amount of pizza two Y is mathematically given by

[tex]Y=\pi r^2[/tex]

[tex]Y=\pi 10^2[/tex]

[tex]Y=314.16inch^2[/tex]

Therefore the second pizza of 10inch is More

Y>X
