This is an isosceles right triangle (AB = BC & ∠ B=90° - Given)
Then the angles at the base are equal and ∠ CAB = ∠ ACB = 45°
Theorem: Segment DE, joining the midpoints of 2 sides is:
1st) parallel to the 3rd side and
2nd) equal to half the measurement of the 3rd side
So if the 3rd side (hypotenuse) = 9 units, DE = 9/2 = 4.5 units
Answer:
18(p-2)
Step-by-step explanation:
We want to factor 
We know that the greatest common factor is 18.
So we can rewrite to obtain:

We factor the GCF to obtain:

Therefore 
Therefore the equivalent expression to 18p-36 is 18(p-2)
Answer:
D
Step-by-step explanation:
Whole numbers are the basic counting numbers: 
Integers are whole numbers and negative numbers: 
Rational numbers are all fractions
where m is an integer and n is a natural number.
Irrational numbers are all real numbers that are not rational.
Number
is irrational number (it is not counting number, so it is not whole number, not integer number), it cannot be represented as a fraction, so it is not rational number, thus this number is irrational number.
The product of integer number -2 by irrational number
is irrational number
