expression represents the area of Dylan’s room
<h3><u>
Solution:</u></h3>
Given that,
Length of room = 
Width of room = 
To find: Expression that the area (lw) of Dylan’s room
Since bedroom is generally of rectangular shape, we can use area of rectangle
<em><u>The area of rectangle is given as:</u></em>
Substituting the given expressions of length and width,
We multiply each term inside first parenthesis with each term inside the second parenthesis.
So it becomes,
Now combine like terms,
Thus the above expression represents the area of Dylan’s room
to write decimal as a percent, multiply by 100
so 0.78 *100 = 78%
The number is -2
-2 + 4 = 2
2 is 2 less than 4
Answer:
Step-by-step explanation:
- Pythagorean theorem
Answer:
a) Here we have:
"In Family A, the youngest child is 7 years younger than the oldest, who is 18"
Let's define:
Y = age of the youngest child.
O = age of the oldest child.
Then we know that:
Y = O - 7
O = 18
Then we can replace the second equation into the first one:
Y = 18 - 7 = 11.
b) Here we have:
"In Family B, the middle child is 5 years older than the youngest child."
Let's define:
Y = age of the youngest child.
M = age of the middle child.
Here we have only one equation:
M = Y + 5.
