The formula for perimeter is
Side a x2 + side b x2
So just multiply 18 by two, and subtract it from 108
Answer:
221
Step-by-step explanation:
area= length times width
13 times 17= 221
Answer:
102 mg
Step-by-step explanation:
Let's convert 28 pounds to kgs.
Since 1 kg = 2.2 pounds, we can find:

So 28 pounds is 12.73 Kg
Since 8mg is given per kg, for 12.73 kg, the amount given should be:
12.73 * 8 = 101.84
Rounded to nearest whole number, that is, 102 mg
Hi there!
Answer:
length = 9 kilometres
Width = 12 kilometres
Let's solve this problem step by step!
To find our answer we need to set up and solve an equation.
Let the length of the rectangle be represented by x.
The width of the rectangle can therefore be expressed by 2x - 6.
The area of a rectangle can be found by using the formula:
A = width × length
Plug in the data from the formula
A = x (2x - 6).
Simplify using rainbow technique.

Now we've found the simplified expression that expresses the area of the rectangle. Therefore, we can now set up and start solve the equation.

Subtract 108

Divide by 2.


Rule AB = 0, gives A is 0 or B is 0.

The length of the rectangle, which was represented by x, must be 9 (since it cannot be a negative number).
Length

Width

Answer:
length = 9 kilometres
Width = 12 kilometres
~ Hope this helps you!
No it cant because a mixed number is over one unless that mixed number is negative
