Answer:
125
Step-by-step explanation:
Answer: D
Step-by-step explanation: y=2 so 2+2=4+1=5
Perimeter is the outside of it and the perimeter is the inside of it, so I'm pretty sure you would have to do both but if u have to do one then I would go with area
Replace every copy of x with 4 and then use the order of operations PEMDAS to simplify
y = -6x+17
y = -6*x+17
y = -6*4+17 ... replace x with 4
y = -24+17
y = -7
Answer: Choice C) -7
Simplifying
5n + 3 = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(n + 2) + 3n
Reorder the terms:
3 + 5n = 2(2 + n) + 3n
3 + 5n = (2 * 2 + n * 2) + 3n
3 + 5n = (4 + 2n) + 3n
Combine like terms: 2n + 3n = 5n
3 + 5n = 4 + 5n
Add '-5n' to each side of the equation.
3 + 5n + -5n = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 + 0 = 4 + 5n + -5n
3 = 4 + 5n + -5n
Combine like terms: 5n + -5n = 0
3 = 4 + 0
3 = 4
Solving
3 = 4
The left and right sides are not equal, therefore there is no solution.
