2(y+6)+3y
Multiply the bracket by 2
(2)(y)=2y
(2)(6)=12
2y+12+3y
2y+3y+12 ( combine like terms)
Answer: 5y+12
Answer:
Area: 12x + 66
Perimeter: 2x + 35
Step-by-step explanation:
Area is the base and the height multiplied, 12(x) + 12(5.5), which is simplified to 12x + 66.
Perimeter is all the sides added together, (x + 5.5) + (x + 5.5) + 12 + 12, which is grouped to be 2x + 11 + 24, then simplified to 2x + 35.
Based on the fact that the sides of the rectangle are in the ratio 5:2, the length of each side is 20cm and 8cm.
<h3>What is the length of each side?</h3>
Based on the ratio, we can assume the a value of x for the perimeter to be:
Perimeter = 2 x ( length + width)
= 2 x (5x + 2x)
= 2 x 7x
= 14x
The value of x is:
56 = 14x
x = 56/14
= 4
The value of the sides are:
= 5 x 4
= 20 cm
= 2 x 4
= 8 cm
