Sure, there's such a thing as an isosceles right triangle. It's what you get when you draw the diagonal of a square. It has one right angle (of course) and two 45 degree angles. It's the shape that vexed the Pythagoreans.
It means to solve, or simplify the expression.
Let's give two examples.
1) 5 + 2²
5 + 4
9 <- We are trying to simplify/solve the expression to as far as we can.
9 cannot be simplified, so the expression has been evaluated.
2) 4x - 5x + 9y
-x + 9y <- Can not be simplified any further so the expression has been evaluated via. combining like terms.
So, because I read the objective, I know it's about perpendicular lines. I know that they have a opposite and negative slope of the original line. So, it would be the last option or (-5, -2)
Answer:730
Step-by-step explanation:
The answer is 40, since 25(2) is 50 and 130-50 is 80. 80/2 is 40
