Answer:
8cm
Step-by-step explanation:
Using the properties of a square, we know that a square has 4 sides, which are all of the same lengths.
Perimeter simply means the sum of all the outer lengths, so all we need to do is 32 ÷ 4, which = 8.
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side (not x) is sqrt(10). Using Pythagoras, we have 10+10=x^2, x=2*sqrt(5)
Answer:
Step-by-step explanation:
9x - 7y = 24
3x + y = -2
9x - 7y = 24
-9x - 3y = 6
-10y = 30
y = -3
3x - 3 = -2
3x = 1
x = 1/3
(1/3, -3)
The first digit can only range from 1-9, resulting in 9 possible options. The next four digits can range from 0-9, resulting in 10 options for each. Since the last two digits remain the same, they do not affect the sample size. Using the fundamental counting principle, we can find the amount of telephone numbers possible in the following equation.
