5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
4m
The area of 4m by 4m is 16 square meters.
4m = 13.12 feet
9m - 14n
5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
4m
The area of 4m by 4m is 16 square meters.
4m = 13.12 feet
4m + 9 + 5m - 12 = 42 Combining like terms to both sides:9m=42+12-9=>9m=45 divide both side by 9:m=5;
(4+9)+(5−1242) = −1224 (I assume m stands for metres?)
-4m + 3 = -8 -4m = -8 -3 -4m = -11 4m = 11 m = 2.75
V = 64 m3
4m
2816-4m = 2812
