Question

Match each expression with the equivalent expanded expression.

-5 (2x + 3/5)
-10x - 3
2 (4x - 2)
30
1/3 (9+81)
x +1.5
-3 (2/3x - 1)
8x - 4
0.5 (2x + 3)
- 2x + 3

Answer 1

Explanation:

`-5(2x + (3)/(5))=2x*(-5) + (3)/(5)*(-5)\\\\= -10x -3\\\\\\2(4x - 2) = 2*4x - 2*2 \\\\= 8x - 4\\\\\\-3((2)/(3)x-1)=(2)/(3)x*(-3)-1*(-3)\\\\=-2x + 3\\\\\\0.5(2x + 3)= 2x*0.5 + 3*0.5\\\\=x +1.5`
