Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!
Answer:
congruency means that the size and shape must be exactly the same in the figures that are compared. A triangle cannot be congruent to a quadrilateral because it has three sides whereas a quadrilateral has four. An isosceles triangle cannot be congruent to a non isosceles triangle because the sides would be different lengths.

Answer:
52
Step-by-step explanation:
when a triangle is similar to another triangle the angles stay the same the only thing that changes are the side lengths.
Answer:
Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.
9x+3y = 36
3y= - 9x + 36
y = -3x + 12
The slope, m = -3
------------------
The slope of lines parallel is the same.
The slope of lines perpendicular is the negative inverse, m = +1/3
----------------
Use y = mx + b and the point (1,2) to find b.
2 = (1/3)*1 + b
b = 5/3
The equation is y = (1/3)x + 5/3 (slope-intercept form)
x - 3y = -5 (standard form)
