Answer:
x= -2, x= -10
Step-by-step explanation:
x^2 + 12x + 36 = 16
Began by setting this quadratic equation to 0. To do this, in this equation you must subtract.
x^2+12x+20=0
Next, we plug this into the quadratic formula, where a in this case is 1(there is nothing in front of x^2), b is equaled to 12(there is a 12 as the coeefficient of 12x), and c is equaled to 20.
The quadratic formula is as goes:
(-b+-(this means plus or minus)√b^2-4ac)/(2a)
After pluggin in and simplifying, the answer is x= -2 and x= -10
Google it.... <em> </em>I just did and there is a video.
Answer:
x equals 30
Step-by-step explanation:
An equilateral triangle adds up to a total of 180 degrees so divided 60 into two and you get 30
88,800÷100=888 because when you are dividing by multiples of 10, the place value always move over to the right depending on how many digits there are.
