A quadratic equation has the standard form:
ax^2 + bx + c = 0
in the given equation,
a = 3
b = -10
c = 5
plug these values into the quadratic formula.
(-b +/- sqrt(b^2 - 4ac)) / (2a)
(-(-10) +/- sqrt((-10)^2 - 4(3)(5)) / (2*3)
(10 +/- sqrt(100 - 60)) / (6)
(10 +/- sqrt(40)) /6
The answer is you multiply 50 times 8 tgen round it to the nearest tenth then you will get 40.0
Answer:
25
Step-by-step explanation:
since the angle in question is across from angle 70, they are congruent. You set up the equation
70=20+2p
50=2p
25=p
