The answer would be D.
The line starts at -2 and has a slope of 2/3 meaning the equation of the linear function would be f(x) = 2/3x - 2.
The top one is x=7 and 4 is y=11 and x=7 idk just bacing it off the other triangles bc there all the same size except 3
Answer:
You would most likely would want to use Pythagorean Theorem, witch is, a²+b²=c²
Answer:
and 
Step-by-step explanation:
This is a quadratic equation, so we start by rearranging its terms so we can apply the quadratic formula:
has two possible solutions given by:

So we rearrange the terms in the given quadratic equation bringing all terms to the left hhand side of the equal sign:

The solutions will then be:

Therefore the two possible answer are:
and
