Step-by-step explanation:
A) opposite sides in a rectangle is always equal
B) 9x+12 = 4x +47
Transpose = 9x - 4x = 47 - 12
solve = 5x = 35
Divide both sides by 5
x = 7
Answer:
a
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
6/3 + 2 x 3
6/3 + 6
2 + 6=8
I guess it is simplifying the expression:
Answer:
missing side: 9x -3
Explanation:
length + width + height = perimeter
4x + 1 + 2x - 4 + height = 15x - 6
6x - 3 + height = 15x - 6
height = 15x - 6 - 6x + 3
height = 9x -3
