Prime numbers are numbers that we can only divide by 1 and it self.
example- 2 can only be divided by 2 and 1
composite numbers are numbers we can divide by two or more numbers
example- 4 can be divided by 1,2 and 4.
Answer:
-13
Step-by-step explanation:
5x − 3y − z
substitute x = −2, y = 2, and z = −3
5(-2) -3(2) - (-3)
multiply
-10 -6 +3
-16 +3
-13
825
You just multiply 1000 × 0.825 = 825 students
It can be x = 3 and x = -15
Step-by-step explanation:
the total surface area is the sum of the individual areas.
we have the ground area : a 6×6 square. = 36 cm²
and we have 4 equal triangles.
the area of a triangle is baseline × height / 2.
which is for each of these triangles
6 × 12 / 2 = 3 × 12 = 36 cm²
so, the total surface area of the pyramid is
36 + 4×36 = 5×36 = 180 cm²
