The correct answer is b.
A polynomial is an expression that contains terms with the form ax^n where a is equal to any number (negative or positive) and n is the power, or exponent, of x (squared, cubed, etc.). In order for it to be a polynomial, the exponent must be positive. Terms that contain square roots are not polynomials as the exponent is considered radical (1/2). Thus, b is the correct answer.
Answer:
11 13 15 17 19
Step-by-step explanation:
We will solve this word problem using 2k+1 which is one of the general forms of an odd integer.
Let 2k+1 be the first odd integer.
(2k+1) + (2k+3) + (2k +5) = (2k+7) + (2k +9) + 3 (the +3 is to accommodate for the left side being 3 more than the right)
Solve for k
6k + 9 = 4k + 19
6k - 4k + 9 = 4k-4k + 19
2k + 9 = 19
2k + 9 - 9 = 19 - 9
2k = 10
2k/2 = 10/2
k = 5
To get the first digit in the series plug in 5 for k
2k+1
2(5) + 1
10 + 1 = 11
So our series is 11, 13, 15, 17, 19
Let's test it.
11 + 13 +15 = 39
17 + 19 = 36
So we are correct, the first 3 integers are 3 more that the sum of the last 2.
I believe it’s The domain of the function is all real numbers less than or equal to -2
Your equation would be x+6x=532. You would add the "x's" together to get 7x=532. You would then divide each side by 7 resulting in x=76. This means Sal's book has 76 pages. To get Lori's book, you just times Sam's by 6 (76×6) which is 456. Lori's book has 456 pages.
I hope this helps you
