Answer:
B
Step-by-step explanation:
One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .
When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.
Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B
Answer:
39
Step-by-step explanation:
quarters are worth $.25. just divide 9.75 by .25 and you get your answer.
9.75 ÷ .25 = 39
Answer:
Here I have attached an image of the graph:
5.986 is already to the nearest thousandth. (see the picture)
C
You can use the pythagorean theorem.
5^2+4^2 =c^2 (or length of AB in this case)
25+16=c^2
41=c^2
c (or length of AB) = sqrt 40
