D. because from b to the horizontal line is 5 units, and to reflect it across the horizontal axis, you would add another 5 units, so you would get a total of 10 units. <span />
Answer:
x(x+13), or x^2+13x
Step-by-step explanation:
You factor one x out, or you can just add the x values.
7*sqrt(3*5*13^2) = 91*sqrt(15) = 91*3.872983346 = 352.4414845<span>

Answer: 25</h3>
Through using the pythagorean theorem, you should find the hypotenuse of the smaller triangle to be 10 units. Therefore, the perimeter of the smaller triangle is 6+8+10 = 24 units.
The perimeter of the larger triangle is 60 units. The ratio here is 24:60 = 2:5
Meaning that the larger perimeter is 5/2 = 2.5 times that of the smaller.
We apply this scale factor 2.5 to the smaller hypotenuse 10 to jump to 2.5*10 = 25, which is the length of the larger hypotenuse.
