When you multiply 12 by -5= You get -60.
For this case we must rewrite the following expression:
We have that by definition of multiplication of powers of the same base, we place the same base and add the exponents, example:
So:
Thus, the expression is rewritten as , using exponents.
Answer:
D is the correct answer because in the description it doesn't say that any of the students dislike a type of ice cream, just that they don't prefer it.
Answer:
x=−6−√105 or x=−6+√105
Step-by-step explanation:
Set the function equal to 0
0=x²+12x−69 Subtract x² from both sides.
0−x²=x²+12x−69−x²
−x²=12x−69 Subtract 12x from both sides.
−x²−12x=12x−69−12x
−x²−12x=−69 Divide both sides by -1.
x²+12x=69 Add (12/2)^2=36 to both sides to complete the square.
x²+12x+36=69+36
x²+12x+36=105 Factor left side.
(x+6)²=105 Take square root of both sides
x+6=±√105 Add -6 to both sides.
x+6+−6=−6±√105
x=−6±√105 Write out both solutions
x=−6−√105 or x=−6+√105
