Answer:
3-2x+1
Step-by-step explanation:
If we indicate x the generic number we can write this expression
3-2x+1
when a sign of an operation is not expressed it means that the operation is multiplication
2x means 2*x
Basically you would break down the numbers let's say you start off with 48, 8 times 6 gives you 48 what can go into 8, 2 and 4 then you say what can go into 4 which is 2 and 2 then break down 6, 3 an 2 basically you break it down all the way until you get the prime numbers
Answer:
y = 45°
Step-by-step explanation:
4 sides = 360°
(2y+1)° + y° + 112° + 112° = 360°
2y + y = 360 - 112 - 112 - 1
3y = 135
y = 135÷3
= 45°
The point is reflected across the x axis. hope this helps you :)
