Answer:
Width = 9 inches , length = 12 inches.
Step-by-step explanation:
Let the width = x inches, then its length x+3 inches.
Perimeter = 2x + 2(x + 3) inches so
2x + 2(x + 3) = 42
4x + 6 = 42
4x = 36
x = 36/4 = 9
So the width is 9 in and length = 9 + 3 = 12 inches.
You are correct.
They both equal 87 and the property is commuting property
Answer:
g(x) = (x-4)² +9
Step-by-step explanation:
If f(x) is moved up 9 units, it becomes x² + 9, as only the 'y' value is changed by 9. Then, if it is moved 4 units to the right, it becomes (x+4)² +9, as only the 'x' value is changed by -4.
