Answer:
1. 7
2. 0
3. 2
4. 14
5. 15
Step-by-step explanation:
You just have to substitute the given variables to the given equation, like so:
2a+3: 2(2)+3= 7
(2 multiplied by 2 is 4 and 4+3=7)
x+y: 1-1=0
6/c: 6/(3)=2
(6 divided by 3 is 2)
(x+2)y: (5+2)2=14
(5 plus 2 is 7, and 7 multiplied by 2 is 14)
a²-b²+c: (4)²- (2)² + 3= 15
(4 multiplied by itself is 16, 2 multiplied by itself is 4 so 16 - 4 is 12 and 12 plus 3 is 15
