In order to use the remainder theorem, you need to have some idea what to divide by. The rational root theorem tells you rational roots will be from the list derived from the factors of the constant term, {±1, ±5}. When we compare coefficients of odd power terms to those of even power terms, we find their sums are equal, which means -1 is a root and (x +1) is a factor.
Dividing that from the cubic, we get a quotient of x² +6x +5 (and a remainder of zero). We recognize that 6 is the sum of the factors 1 and 5 of the constant term 5, so the factorization is
... = (x +1)(x +1)(x +5)
... = (x +1)²(x +5)
_____
The product of factors (x +a)(x +b) will be x² + (a+b)x + ab. That is, the factorization can be found by looking for factors of the constant term (ab) that add to give the coefficient of the linear term (a+b). The numbers found can be put directly into the binomial factors to make (x+a)(x+b).
When we have 1·5 = 5 and 1+5 = 6, we know the factorization of x²+6x+5 is (x+1)(x+5).
Answer:
12 + 10 + 15,62= 37,62
Step-by-step explanation:
According to the Pythagorean Theorem, you will have this:
* There was an error in the correct answer, so I corrected it, as you can see.
I am joyous to assist you anytime.
To calculate this, we need to do the following:
92 * 115 = 10580 (we first multiply the percentage with our number)
10580 / 100 = 105.8 (and divide what we get by 100 to get the final answer)
And this is also already the answer: 105.8
Answer:
4 oranges.
Step-by-step explanation:
First, you find the unit rate of cost per orange, which is $0.70, then divide that by $2.80.
Answer:
9/10
Step-by-step explanation:
1/6 hour for 3/20 of his yard
6/6 hour or 1 hour = 6* 3/20 = 9/10 of his yard per hour
