Answer:

10b²

Step-by-step explanation:

First, let's look at the coefficients. The greatest common factor of all three numbers 30, 80, and 20, is 10. Now, let's look at the variables. All three terms are divisible by b² (with no remainder). We can combine 10 and b² so they become one term, and that is the GCF. 10b².

Bashir works in a weather station and has launched a weather ballon. The height of the baloon is 4 kilometers and it is 1 kilome

Answer:

Explanation:

We are given that the height of the balloon is 4 km and that it is 1 km away from the station.

Setting up the diagram that describes the given scenario, we would end up with a right-angled triangle as the one shown in the attached image

where:

height of the balloon = 4 km represents one side of the triangle

distance between the base of the balloon and the station = 1 km represents the other side

distance between the balloon and the station is the length we want to find and it represents the hypotenuse of the triangle.

To get the length of the hypotenuse, we will use the Pythagorean theorem
