Two expressions for the perimeter of a square are:
4a
- a represents one side of the square
a + a + a + a
- a representa one side of the square
the first expression does not include any addition. But the two expressions are actually equivalent.
The answerd is 197 because I estamited 37X5 to 40X5 is 200 than 200-3 is 197
Answer:
(C) 2
Step-by-step explanation:
Given equations 2a + 7b+2c=16 and 2a + 3b +2c= 8, you want to know the value of b.
<h3>Solution</h3>
The coefficients of 'a' and 'c' are the same in the two equations, so we can eliminate those variables by subtracting one equation from the other. We can keep the resulting coefficient of 'b' positive if we subtract the second equation from the first.
(2a +7b +2c) -(2a +3b +2c) = (16) -(8)
4b = 8 . . . . . . . simplify
b = 2 . . . . . . . divide by 4
D because your x value is 6
