In each quantity (the area where the parenthesis are), you must distribute the outside number to each term on the inside. -6 multiplied by x is -6x. -6 multiplied by 3 is -18 (always remember that if one factor is negative, then your product is negative. If both factors are negatives, then your product is positive). -(1/4) multiplied by 4x is -1x or -x. -(1/4) multiplied by -8 is 2. Add all your values together. The values with x's may only multiply to other values with x's.
-6x-1x-18+2
Combine the x values(add)
-7x-18+2
Combine regular numbers(add)
-7x-16
This is your final answer.
The formula for the slope of a straight line is the change in y divided by the change in x. Since the y axis is equal to mass, and the x axis is equal to volume, slope is equal to mass divided by volume. Therefore, the slope of a mass versus volume graph is equal to density.

Because the rock making up continental plates is generally lighter and less dense than oceanic rock, it is too light to get pulled under the earth and turned into magma. Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.
<span>At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
