You are gonna use the distributive property.
4(2.5g - 4) + 3(1.2g - 2)
So you are going to multiply 4 with everything inside the first set of parenthesis and your gonna multiply 3 with everything insides the second set of parenthesis.
4 x 2.5g - 4 x 4 + 3 x 1.2g - 3 x 2
10g - 16 + 3.6g - 6
You wanna combine like terms:
10 - 3.6g + 16 - 6
6.4g + 10
You answer is 6.4g + 10.
Hope this Helps!!
