6x^2 + 23x - 4 = 0
factorising:-
(6x - 1)(x + 4 ) = 0
x = 1/6 , - 4
Answer: OPTION B
Step-by-step explanation:
You have the following expresion:

Mulitply them, then:

Now, descompose the number inside the square root into it primes factor to simplify the expression:
75=5*5*3=5²*3
Substitute:

Simplify. Then, you obtain:


A quick way to do this is:

Therefore the temperature rose 6 degrees Celsius. I hope this helps! =)
Answer:
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A=πrl , where l is the slant height of the cone .
