We have the following equation:
ax2 + bx + c = 0
Using the resolver we have:
x = (- b +/- root (b2 - 4ac)) / 2a
We have:
b2 - 4ac <0
Therefore the root is negative
Answer:
It has two complex solutions
option B
509-3a=209
509-509-3a=209-509
-3a=-300
-3a/-3=-300/-3
a=100
Your age is 100 years old.
Check:
509-3a=209
509-3(100)=209
509-300=209
209=209
60
Because 85% of 60 is 51
To find the unknown you just do 0.85/51
Answer:
-2.5
Step-by-step explanation:
-2.5 is greater.
Answer:
Step-by-step explanation:
We know there are 180° in EVERY triangle. Given one angle is 58°
This triangle shown has two sides that are the same, both are 6. The value of those two sides is irrelavent, except for the fact that this is an Isosceles triangle and the angle opposite those two sides are equal.
x + x + 58 = 180
2x + 58 = 180
2x = 180 -58
2x = 122
x = 61
