Answer:
Area: 5x + 10
Perimeter: 2x + 14
Step-by-step explanation:
Area = length times width
Perimeter = length (2) + width (2)
<u>Area:</u>
Multiply the length be the width. That gives you 5 (x + 2).
Then use the distributive property to simplify this expression. That gives you 5x + 10.
<u>Perimeter:</u>
Multiply the width by 2. That gives you 10.
Multiply the length by 2. That gives you 2x + 4
Add the 2 together. That gives you 10 + 2x + 4.
Combine all like terms. That gives you 2x + 14.
Answer:
3(9m + 13) - (m + 10) = 1
Step-by-step explanation:
Here, we want to write an equation we can use to find the age of Mario.
Let the present age of Mario be M
Age of Sarah is 3 years older than 9
times Mario’s age
Mario’s age is thus;
9m + 3
In ten years, she will be 1 less than triple his age
In 10 years time, sarah age will be 9m +
3 + 10 = 9m + 13
Mario age will be m + 10
Mathematically;
3(9m + 13) - (m + 10) = 1
The value of y would be 5.
