Use algebra tiles to model the expression, and then combine like terms. Check all that apply.

3 + 2 + x + x
Combine the x tiles and the integer tiles.
Combine all the tiles.
The equivalent expression is 5 + 2x.
The equivalent expression is 7x.
Use substitution to verify the expressions are equivalent.

Answers

Answer:

1 and 3

Step-by-step explanation:

option 4 isn’t correct because you can’t combine 5 and 2x. You could if the 5 had an x too

the last one isn’t correct because you aren’t substituting anything

the second isn’t correct because you aren’t combining them all together. You are only combining the ones that are like-terms

Step-by-step explanation:

The equation for volume of a rectangular prism is lwh. We have the lh and 6 times 9 is 54. Now we just divide 162 and 54 and that's the width which is 3. And to double check 3 times 9 times 6 is 162 :)

Find the radius of a circle where the area of the circle equals the circumference of the circle.

Answers

Answer:  Radius = 2

======================================================

Explanation:

For a circle with radius r, we have these formulas

area = pi*r^2 circumference = 2*pi*r

Equate the two expressions and isolate r

pi*r^2 = 2*pi*r

pi*r^2 - 2*pi*r = 0

pi*r(r - 2) = 0

pi*r = 0 or r - 2 = 0

r = 0 or r = 2

A radius of 0 doesn't make much sense, so we ignore it. The only possible answer is r = 2.

-------

If the radius is 2, then,

area = pi*r^2 = pi*2^2 = pi*4 = 4picircumference = 2*pi*r = 2*pi*2 = 2*2*pi = 4pi

Both result in 4pi to help confirm our answer.

Set up and equation
Circumference = area
2pi•r = pi•r^2
Solve for r
2pi/pi = r^2/r
2=r
