Answer:
Step-by-step explanation:
"quaratic" should be "quadratic."
The coefficients of this quadratic are 4, 2 and -1. Thus, the discriminant is
b^2 - 4ac, or here, 4 - 4(4)(-1) = 20
Since the discriminant is positive, our quadratic has two real, different roots.
-2 ± (√4)(√5)
The roots are: x = ---------------------
2(4)
-1 ± √5
This reduces to x = ---------------
8
A the answer is 1296 but 756 is squared so it is A ok thats easy i did that in 7th grade finally something i can do
green or the one that is on the rught and lowest and the lowwst part is at(4, -3)
Step-by-step explanation:
its is this becaue the equation is y=x^2-8x+13

8/3 is an improper fraction, to make it proper you find out how many times 3 goes into 8 (which is 2). So then you have 2 and two times 3 is 6. This does not equal 8 yet so you do 8-6=2 You put this number over the denominator 3. So your final answer is 2 2/3.
Answer:
MB // HG by the converse of the Corresponding Angles Theorem ⇒ C
Step-by-step explanation:
Two lines are parallel if intersected by a line and formed one of these types of angles.
- Corresponding angles equal in measures (shaped letter F)
- Alternate angles equal in measures (shaped letter Z)
- Interior supplementary angles, the sum of their measures is 180° (shaped letter U)
In the given figure, there are 4 lines intersected
∵ Lines MB and HG intersected by line BG
∵ There are two angles marked by the same mark
∴ They are equal in measures
∵ They are in the corresponding position
∴ Lines MB and HG are parallel
∴ MB // HG by the converse of the Corresponding Angles Theorem
