Sqrt of 36 an 49.
6<?>7
?=the sqrt of 42.
Answer:
273.7
Step-by-step explanation:
first fine the sides that isn't the base.
triangle area formula: (b*h)/2
(14*9)/2 = 63
since there are 3 sides you multiply this by three.
63*3=189
then find the base.
same formula since its a triangle.
(12.1*14)/2 = 84.7
now add them both up:
84.7+189 = 273.7
hope this helps!

B
Step-by-step explanation:
![3 \times \frac{1}{2} = \frac{7}{2}](https://tex.z-dn.net/?f=3%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B7%7D%7B2%7D%20)

Answer:
Step-by-step explanation:
The discriminant is what's under the square root sign in the quadratic equation. The equation for the discriminant is
, where b is the coefficient of x, a is the coefficient of
, and c is the number with no variable attatched to it. If we plug in the numbers (
) it gives you 241, which is the discriminant. Since 241 is more than zero, it has 2 zeros. If the discriminant was 0, there'd be 1 zero, and less then zero there would be zero zeros.
