Answer:
So it gives you a little picture and tells you what would the question be if you had this graph.
Step-by-step explanation:
The correct answer would be B, find the area because the 4x + 3 is your length and 3x is your length, A = length * width. So the answer is B, find the area.
Slope formula
y2-y1/x2-x1
5-3/2-4
2/-2
-1 = slope
y=-1x+b
5=-1(2)+b
5=-2+b
b=7
Your answer:
y= -1x + 7
I don't see anything, but any line that doensnt have the right angle sign is not perpendicular.

The percent error is -2.1352% of Jocelyn's estimate.
Isosceles right triangles have two equal sides (a and b) that are not the hypotenuse (c). And when two sides are equal, so are their opposite angles. There are only 180° degrees in any triangles, thus the right angle = 90°, so 90 left for the two equal, means that 2x=90,
x = 45°.
There are several ways to go about solving a triangle like this. The best and easiest is simply to memorize that the hypotenuse is exactly root2 times the other sides. Or, each isosceles side is the hypotenuse (c) ÷ root2

Another way to do it is the longer proof of Pythagorean Theorem:
