Drag the tiles to the correct boxes to complete the pairs. not all tiles will be used.
match the expressions to their verbal descriptions. assume that all variables represent integer values and that none are equal to each other.

First expression ⇒ m + 3(m - 11)²

Second expression ⇒ m(-8m)

Third Expression ⇒ -3mn²

Fourth Expression ⇒ m - 7mn

Step-by-step explanation:

* The sum of m and a n term depending on m

m added to the term 3(m - 11)²

* The product of m and a multiple of m

m multiplying by its multiple (-8m)

* The product of m and a factor not depending on m

m multiplying by (-3n²) which is a factor not depending on m

* The difference between m and a factor depending on m

(-7mn) is a factor depending on m and subtracted from m

828. all there is to it!

here, if you ever need with rounding (or other forms of arithmetic/math) again, use this:

thats the rounding one, but if you just click the top left, it shows you all the calculators you may need!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
