The expression is
5x + 5y
We are to prove that it is an odd integer when x and y are integers of opposite parity
First, we can assume
x = 2a (even)
y = 2b + 1(odd)
subsituting
10(a + b) + 5
5 [(2(a + b) + 1]
The term
2(a + b) + 1 is odd and the result of an odd number multiplied by an odd number is odd
Answer:
Hello! answer: 252
Step-by-step explanation:
To find parelogram area you do base × height so... 21 × 12 = 252 therefore 252 is the area Hope that helps!
Answer: (-4,-8)
Step-by-step explanation: I got a 100% on the quiz
Answer: x=- 8 or x=2
Step-by-step explanation:
1. To solve this problem you can applly the quadratic formula, which is shown below:

2. The quadratic equation is:

3. Then:
a=1
b=6
c=-16
4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:


Dividing by 100 shifts each digits two paces because 100 has two zeros.
Each 0= a digit shifts to the right
