What is this, (2r-1)(r-1)? I'm so confused.

Answers

Answer 1

Answer:

It looks like the factored form of a polynomial

Step-by-step explanation:

In unfactored form, it would be this:

2r^2 + -2r + 1

Answer 2
(2r-1)(r-1)
=2r(r-1) -1(r-1)
= 2r^2-2r-r+1
=2r^2-3r+1

Answers

Answer:

1/ 6

7/ 12

Step-by-step explanation:

Answer:

7a) 1/7

7b) 7/12

Step-by-step explanation:

For 7a) you know that the denominator of 5/6 is equal to 6 so that means you should make 1 have a denominator of 6. To do that, you have to multiply the denominator and the numerator by 6 to get 6/6-5/6=?. With this, you could easily solve the two fractions because they have equal denominators. You subtract the numerator and keep the denominator. 6-5=1 so the answer is 1/6.

For 7b) I would first convert 1 3/12 into an improper fraction. To do that, you have to multiply the whole number by the denominator then add the numerator. It will look like this 12x1+3/12 which is equal to 15/12. This makes the question easier to solve. You then want to convert 2/3 to have a denominator of 12. To do that, you have to multiply 4 on the numerator and denominator. This will turn the fraction into 8/12. After you do that, you can easily subtract the fractions again. you do 15-8/12 which is equal to 7/12.

QR is a radius of circle R and PQ is tangent to circle R. Find the value of x.

Answers

Answer:

x = 13

Step-by-step explanation:

using the Pythagorean theorem

x² = 85² - 84²

x² = 7225 - 7056 = 169

x = 13

Answer:

x = √(85²-84²)

x = √(7225-7056)

x = √169

x = 13

Explanation:

A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.

Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.

y = 3x +1y -7 = 3(x -2)

If we subtract the first equation from the second, we get ...

  (y -7) -(y) = (3(x -2)) -(3x +1)

  -7 = 3x -6 -3x -1 . . . . . eliminates y

  -7 = -7 . . . . . . . . . true for all values of x

There are an infinite number of solutions.

A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism

Answers

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.

The required circumference of the given circle is 25.12 cm as shown figure.

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have been given data as follows:

The radius of the circle (r) = 4 cm

Circumference of the circle = 2πr

Substitute the values in the above formula and we get

Circumference of the circle = 2π(4)

Circumference of the circle = 3.14(8) = 25.12 cm

The required circumference of the given circle is 25.12 cm.

Write a real word problem that involves dividing a decimal by a whole number

Answers

There is 75% of a pizza and there are 3 siblings who want to eat it for lunch. They divide what they have of the pizza evenly among themselves. In terms of a whole pizza, what percent did each sibling get.

This question would mean dividing 75% or .75 by 3 which would mean each person got 25% or .25 of what would be a whole pizza.
So while each person would get .33 of the current sized pizza (.75) in terms of a whole pizza it would be .25

I hope this makes sense! Sorry if I over explained it.

Find Arc PR
Please help and give explanation ​

Answers

Arc PR is 156 degrees. Since both angles are are making the forming arc they should be congruent. You can put (5x+23)=(9x-21) which is x=11.
Then you plug in 11 into your equation; 5(11)+23=78.
Since the vertex is on the outside of the circle then the arc is forms is 2 times the value of the angle.
78(2)=156
