Explanation: the first thee are the fractions times the number in the parentheses. The last two are doing 10 divided by the fraction to get x. It's just reverse of the first three, because you have to find x in a different order, so you use division. Hope this helps.

Answer: 296 cubic in.
Step-by-step explanation: Since we are talking about cubes, and you know the volume of a cube is lwh, we know l, w and h are all equal, meaning be can cube root the volume to find all side lengths. The cube root of 216 is 6, so if each side in cube B is 2 longer, then the lwh for B is 8*8*8, or 512. 512-216=296.
Answer: 14x^2-93xy+60y^2 Hope that helps!
Step-by-step explanation:
1. Expand by distributing terms
(20x-12y)(x-4y)-(3x-4y)(2x+3y)
2. Use the Foil method:(a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(3x-4y)(2x+3y)
3. Use the Foil method : (a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(6x^2+9xy-8yx-12y^2)
4. Remove parentheses 20x^2-80xy-12yx+48y^2-6x^2-9xy+ 8yx+12y^2
5. Collect like terms (20x^2-6x^2)+(-80xy-12xy-9xy+8xy)+(48y^2+12y^2)
6. Simplify.
And your answer would be 14x^2-93xy+60y^2
