Answer:
x²+2x-3=0
According to Vieta's formula:
x²-(Sum of roots)x+(product of roots)=0
Sum of roots=-3+1=-2
Product of roots=-3×1=-3
The equation is x²-(-2)x+(-3)=0
x²+2x-3=0
Answer:
A.) 40°
Step-by-step explanation:
A triangle is equal to 180°
Angle X and Y has the same angle, so both have 70°.
So:
70° × 2= 140°
To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.
So:
180° - 140°= 40°
Answer= 40°
I hope this helps! :)
It's like simple math but the sign of the answer would be the opposite.
|−19−(−14)|
|−19 + 14|
|- 5|
|- 5| = 5
If you round 5.066 to the nearest hundredth it would be 5.07
