Answer:1440 degrees
Step-by-step explanation:
The interior angles of a decagon is 1440 degrees. All sides are the same length (congruent) and all interior angles are the same size.
1 meter has 100 CENTImeters.
now, 85cm is not longer than 1 meter clearly, because 100 cm > 85 cm.
so one can say, that is 1 meter is longer by 15cm instead.
100 - 85 = 15.
Answer:
18cm
Step-by-step explanation:
We have the length of the rectangle but we need to find the width which we'll call w. Area is a, l is length.
a = l * w
20 = 5 * w
divide both sides by 5 to cancel the multiplication by 5 on the right side
4 = w
The rectangle is going to have two sides that are the length of l, and two sides that are the the length of w. We're looking for the perimiter p.
p = 2l + 2w
p = (2 * 5) + (2 * 4)
p = 18

Step-by-step explanation:
Remember that in order to find the slope of two points you need to substitute the variables and subtract making sure you keep the 2's and the 1's together.

Answer: 
Step-by-step explanation:
By the negative exponent rule, you have that:
By the exponents properties, you know that:
Therefore, you can rewrite the left side of the equation has following:
Descompose 32 and 8 into its prime factors:
Rewrite:
Then:
As the base are equal, then:
Solve for x:
