1 Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.
Expand or factor each of the following expressions to determine which expressions are equivalent.
(3:+ 2)(932
6x + 4)
(3x + 5)(3.1 – 4)
(42 – 3y)?
(3x − 2)(9.12 + 61 + 4)
932 – 24ry + 16y2
27x3 - 8
(31 – 4y)?
9x2 + 3x - 20

answer: 1 and 3

step-by-step explanation:

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.
