Step-by-step explanation:
A triangle with a base of 2 and a height of 3.
Double the base and it becomes 4, and double the height and it becomes 6.
Area of the new figure = 1/2 * base * height = 1/2 * 4 * 6 = 2 * 6 = 12
The area of a towelette with double the base and double the height is 12 inches^2.
is 12.5 ok I think ,......................,,,,,,
I'm thinking this is what the problem looks like:
. The first thing to do is to move the
over to the other side because it has a common denominator with the other side. Doing that and at the same time combining them over their common denominator looks like this:
. The best way to solve for x now is to cross-multiply to get 3(4-x)=-4(x-4). Distributing through the parenthesis is 12 - 3x = -4x + 16. Solving for x gives us x = 4. Of course when we sub a 4 back in for x we get real problems, don't we? Dividing by zero breaks every rule in math that there ever was! So, yes, the solution is extraneous.
We saw under Functional Notation that y = 3x + 2 and f (x) = 3x + 2 can be interpreted as equivalent notations, where y has been replaced by f (x), or y = f (x). In y = 3x + 2, we see “y as a function of x”
