Step-by-step explanation:
4x2+8x−3=0
For this equation: a=4, b=8, c=-3
4x2+8x+−3=0
Step 1: Use quadratic formula with a=4, b=8, c=-3.
x=
−b±√b2−4ac
2a
x= −(8)±√(8)2−4(4)(−3)
2(4)
x= −8±√112
8 x=−1+
1 2 √7 or x=−1+
−1 2 √7
Answer: x=−1+
1 2√7 or x=−1+
−1 2 √7
25-9=16 so 16 is the answer
Answer:
The correct answer is 54.
8y - 2 = - 18
8y = - 16
y = - 2

Answer:
The temperature in Kelvin corresponding to F degrees Fahrenheit is 
Step-by-step explanation:
Given : One can convert temperature from Kelvin into Fahrenheit using the formula
.
To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?
Solution :
Temperature from Kelvin into Fahrenheit is given by,

Writing Kelvin in terms of Fahrenheit,
Subtract 32 both side,

Divide by 95 both side,

Add 273 both side,

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is
