These questions are SOOO easy, but I just don't have a clue. (don't even know if they technically are algebra they are that easy).
x² - 8x - 20 =
(x+10) (x-2)
Thats what I got for that answer (lucky guess) but how do you know which side each sign goes on.. ie (x+10)(x-2) or (x+2) (x-10)??
Same problem with this question...
(x-6) (x-5) =
x² - 11x + 30
The shortest side of the triangle lies opposite the smallest angle.
Therefore
5. Answer: AC
6. Answer: AB
A = lw + 0.5bh
0.5bh = A - lw
b = (A - lw)/0.5h
option B is the correct option.
Answer:
vertex is (4,-25)
Step-by-step explanation:
To find out the vertex we use formula
From the given f(x), the value of a=1, b=-8 and c=-9
Plug in the values in the formula
x=4
Now find the value of y
plug in 4 for x in f(x)
The value of y is -25
The vertex is (4,-25)
