X² - 16x =23

16/2= 8; 8²=64       add 64 to both sides of the equation

x² - 16x + 64 = 23 + 64

the answer is D.

How do you divide a fraction
sveta [45]
Hey, 25equivelv!

If you know how to multiply a fraction, you will be able to divide it as well. If you do not know how to multiply a fraction, look it up or message me.

I say that if you know how to multiply fractions you know how to divide them because dividing is basically multiplication backwards, so in fraction terms, it's multiplying by the reciprocal. If you don't know what that is, multiplying by the reciprocal is that same as flipping the second fraction and multiplying.

Sphinxa [80]
If we have 2 dices rolling, we have all 6x6=36 different ways.
But for the sum of the two being 4, we have (1;3), (3;1) and (2;2), only 3 ways.
And we calculate the probability : 3:36= 1/12
