Answer:
B. The result is not correct because Step 2 has an error.
Step-by-step explanation:
6x+5=3(2x+1) Distribute on the right side
6x+5=6x+3
-6x -6x Subtract 6x from both sides
5≠3 There is no solution because 5 doesn't equal 3
The reason Paloma's result is wrong is because you can't subtract 3 from 5 and set it equal to 0
Ex: 5-3 = 0 2 = 0
Perimeter refers to the distance around a figure in this case a rectangle. On this problem is given the perimeter of the rectangle and its asked to find the value of x.
First of all, you should know that the formula to find the perimeter of a rectangles is P=2b+2h where b is the base and h the height of the rectangle.
P=2b+2h Substitute the given values
30=2(3x)+2(2x) Associate the terms
30=6x+4x Combine like terms
30=10x Divide in both sides by 10 to isolate x
3=x
The value of x for the rectangle is 3 units.
