Answer:
The correct option is C.
Step-by-step explanation:
In a triangle, then sum of two smaller sides is greater than the length of third greatest side.
Let, in a triangle ABC, If the length of sides are
, then

In option A,

Therefore option A is incorrect.
In option B,

Therefore option B is incorrect.
In option C,

Therefore option C is correct.
In option D,

Therefore option D is incorrect.
It mean benchmarks in out side of math

Answer:
D 112
Step-by-step explanation:
bc i know
The discriminante :
b^2-4ac
1^2 - 4 * -2 * -28 = 1 - 224 = -223
When the discriminant (b^2-4ac) is less than 0, the equation had no real solutions.
-223<0, so, 2x^2+x-28 = 0 has no real solutions.
Hope that helps :)
Answer:
C
Step-by-step explanation:
y=x is a line that has slope 1 meaning it go ups (increases) from left to right.
So that puts us at choice A or C.
Both A or C differ by the numerator for the other function.
We can find the x-intercept for A and C by setting the numerator equal to 0 and solving for x.
Let's do that:
A: -x-10=0 C. -x+10=0
-x=10 -x=-10
x=-10 x=10
A says x-intercept -10
C says x-intercept 10
Your graph intercepts the x-axis at 10 so the answer is C.
