A number has only 1 factor pair. One of its factors is twice the other factor. What is the number? Explain.
Mrrafil [7]
<h3>Answer:  2</h3>

========================================================

Explanation:

If a number only has one factor pair, then that number must be prime. This is because prime numbers only have factors of 1 and the number itself.

For instance, the value 7 is prime because the only factors of this are 1 and 7.

For something like the number 32, it is composite and not prime because it has the factors {1,2,4,8,16,32} and it leads to these three factor pairs: 1*32, 2*16, 4*8. This is one example showing why the answer isn't composite.

-----------

Let's say that p is the unknown prime we want to find. The factors of this are 1 and p. We're told that "one of the factors is twice the other factor", so that must mean p = 2*1 = 2. We can see that 2 is twice that of 1.

WHat is the missing height?
ololo11 [35]

Answer:

w = 4 cm

Step-by-step explanation:

recall that the area of a triangle is given by

A = (1/2) x base length x height

we are given:

A = 10 cm²

base length = 5 cm

height = w

substituting the values above into the equation,

A = (1/2) x base length x height

10 = (1/2) x 5 x w

20 = 5w

w = 20/5

w = 4 cm
