As you might be known that the opposite sides of a rectangle are equal.
so,
the perimeter of a rectangle becomes
length + breadth + length + breadth
2 length + 2 breadth
2 (length + breadth)
apply the terms,
2 (3x +5 + 3x^2+ 6x -10)
= 2 ( 3x^2 +9x -5)
= 6x^2 + 18x -10 units.
Answer:
x=0
Step-by-step explanation:
- 7(x + 4) - 4= - 32
Add 4 to each side
- 7(x + 4) - 4+4= - 32+4
- 7(x + 4) = - 28
Divide by -7
- 7(x + 4) /-7= - 28/-7
x+4 = 4
Subtract 4 from each side
x+4-4 = 4-4
x=0
A. y=-1.5x+30
