Answer:
D. obtuse isosceles
Step-by-step explanation:
An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle). It is not possible to draw a triangle with more than one obtuse angle. Note: It is possible for an obtuse triangle to also be scalene or isosceles. An equiangular triangle has three congruent angles.
1.) (x - 4)(x + 1) = 0
x^2 + x - 4x - 4 = 0
y = x^2 - 3x - 4
2.) (x - 2)(x - 6) = 0
x^2 - 6x - 2x + 12 = 0
x^2 - 8x + 12 = 0
since the function has a maximum point the leading coefficient is negative.
Therefore, required equation is y = -3x^2 + 24x - 36
3.) a(x + 3)^2 = ax^2 + 6ax + 9a
since the y intercept is at y = 18 => 9a = 18 => a = 2
Therefore, required function is y = 2x^2 + 12x + 18
(Scroll to the bottom to see my answer) The order of operations is PEMDAS aka Parentheses. Exponents. Multiplication or Division (Which ever come first). Addition or Subtraction (again whichever comes first). Start with (12-9)=3 then multiply 3 by 3, three times=9 then multiply 2 and 7 together=14 then do 9-14=-5
So my final answer is -5! I might be wrong but I did my best! I hope I’m not too late!
The first one is eight 4400-2400=2000 2000/250=8
