Answer:
y = 3
Step-by-step explanation:
The left side has to equal the right side
10 = 2y+4
Subtract 4 from each side
10-4 = 2y+4-4
6 = 2y
Divide each side by 2
6/2 = 2y/2
3 = y
Answer:
y = 3.
Step-by-step explanation:
Since we know that this is a rectangle, this means that there are two pairs of parallel and congruent sides.
If the width of the rectangle equals 10, then 2y + 4 must equal 10.
Solve for 'y':
10 = 2y + 4
6 = 2y
y = 3.
