The correct answer to this is 70
Answer:
You did not post the options, but i will try to answer this in a general way.
Because we have two solutions, i know that we are talking about quadratic equations, of the form of:
0 = a*x^2 + b*x + c.
There are two easy ways to see if the solutions of this equation are real or not.
1) look at the graph, if the graph touches the x-axis, then we have real solutions (if the graph does not touch the x-axis, we have complex solutions).
2) look at the determinant.
The determinant of a quadratic equation is:
D = b^2 - 4*a*c.
if D > 0, we have two real solutions.
if D = 0, we have one real solution (or two real solutions that are equal)
if D < 0, we have two complex solutions.
Does 0.007/10=0.07
true or false?
Answer:
NO if you wanted to get 0.07 you would have to multiply not divide.
Step-by-step explanation:
0.007/10=0.0007
Answer:
B: 5x + 3
Step-by-step explanation:
(f+g) (x) = f(x) + g(x) = (2x -6 ) + (3x + 9) = 5x + 3
Step-by-step explanation:
Hence it is a triangle So sum of all the angels of triangle is equal to 180°
Then
5x + 6x + x = 180°
12x = 180°
x = 180° / 12
x = 15°
5x = 5*15°= 75°
6x = 6* 15° = 90°
x = 15°
Hope it helps :)
