If is an integer (a whole number), then the expression represents an even number, because even numbers are the multiples of 2. The expressions 2 n − 1 and 2 n + 1 can represent odd numbers, as an odd number is one less, or one more than an even number.
Answer:
8 x^5 y^7
Step-by-step explanation:
Simplify the following:
4×2 x^2 y^3 x^3 y^4
Hint: | Combine products of like terms.
4 x^2 y^3×2 x^3 y^4 = 4 x^(2 + 3) y^(3 + 4)×2:
4×2 x^(2 + 3) y^(3 + 4)
Hint: | Evaluate 3 + 4.
3 + 4 = 7:
4×2 x^(2 + 3) y^7
Hint: | Evaluate 2 + 3.
2 + 3 = 5:
4×2 x^5 y^7
Hint: | Multiply 4 and 2 together.
4×2 = 8:
Answer: 8 x^5 y^7
Perimeter= 2(length+width)
60= 2(l+w)
l=2w
Substitution method
60= 2(2w+w)
60= 2(3w)
30= 3w
10= w
Plug the value of w in.
l= 2(10)
l=20
Final answer: Length= 20, width=10
So first you have to get 3.4% more vehicles from 975 you do this by multiplying 975 by .034 , which equals 33.15 but we will round to 33 . After that you add 33 to 975 and you get 1,013. Now you have to add 3.4% again because the problem says it happens every year so 1,008 multiplied by .034 equals 34.272 but we will round to 34. So now adding the 34 to 1,008 you get 1,042. The answer is C , 1,042 vehicles.
