Basically you multiply the original length by the scale factor. So let's say there's a side length of 10 and the scale factor is .5, then you multiply 10 by .5 and get 5, that's all scale factor is . It can get larger/smaller, just depends on the number.
Yes, (3, 2) is a solution to y = 2x - 4. (:
I don't really grab the concept of this but it's basically numbering the graph ang filling the coordinates in the x and y spaces
y=4/-2+ x=5/-3
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
A = LWH
/WH = L
Therefore L = A / WH
