As per the problem,
Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.
We have been asked to find , which expression can be used?
As per the distributive property , we know that
Now apply this on the given expression we get
Hence the expression , which can be used is 17(69+31)
Answer:
15 cm, 15 cm, 11 cm
Step-by-step explanation:
let the equal sides be x then the third side is x - 4
The perimeter is the sum of the 3 sides and is 41 cm , then
x + x + x - 4 = 41
3x - 4 = 41 ( add 4 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
x - 4 = 15 - 4 = 11
The sides are 15 cm, 15 cm, 11 cm
the mean can be misleading, because there outlier (77), which is not close to the ages of the others, thereby changing the mean drastically.
hope this helps
The first thing to do is to work out the biggest number that goes into bother 24 and 3. As the only that goes into three- other than 1- is itself, one can assume this is the number we are looking for.
Next, divide bother numbers by 3.
24 / 3 = 8
3 / 3 = 1
You now take 3 out of the brackets, and leave 8 and 1. 24x / 3 = 8x.
3(8x + 1)
