Since these are right triangles you can use the pythagorean theorem
a² + b² = c²
a = one leg of the triangle
b = the other leg of the triangle
c = the hypotenuse
1. 4² + 3² = c²
16 + 9 = c²
25 = c²
√25 = √c²
5 = c
c = 5cm
2. 5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = √c²
13 = c
c = 13in
4. 7² + 9² = c²
49 + 81 = c²
130 = c²
√130 = √c²
11.4 = c
c = 11.4cm
5. a² + 10² = 15²
a² + 100 = 225
a² = 125
√a² = √125
a = 11.2ft
You answer is going to be -966x^3
Answer:

Step-by-step explanation:
A proportional relationship has equation:

where k is the constant of proportionality.
Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.
We substitute k=-10 into the equation to get:

Therefore the correct choice is

Answer:

Step-by-step explanation:
Hello!
The HCF or the highest common factor (sometimes also known as the greatest common factor, GCF), is the greatest factor between terms.
First, let's expand both terms:
If we keep them on top of another, we can see that the overlapping variables are
, meaning that the greatest common factor between them is
.
