Solve for x: x^2 + 28x = 60
Alisiya [41]

For this case we have a quadratic equation, x ^ 2 + 28x-60 = 0, of the form ax ^ 2 + bx + c = 0

Where:

a = 1\\b = 28\\c = -60

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.

These numbers are:

+30\ and\ -2\\+ 30-2 = + 28\\+ 30 * -2 + -60

Then, the factorization is given by:

(x-2) (x + 30) = 0

The roots are:

x_ {1} = 2\\x_ {2} = - 30

Answer:

x_ {1} = 2\\x_ {2} = - 30

The temperature of a hot steak starts at 140f and decreases at 5f per minute what will the temperature of this steak after a cer
irina1246 [14]

Answer:

T(m) = (140 - 5m)

Step-by-step explanation:

Given that :

Initial temperature, a = 140 F

Rate of decrease = 5 F per minute

Given a certain Number of minutes, m

Temperature, T after m minutes ;

Using the formula :

Final temperature = Initial temperature - 5*number of minutes)

T(m) = (140 - 5m)

Given that ; m = 10

T(10) = 140 - 5(10)

T(10) = 140 - 50

T(10) = 90 F
