Answer:

(f+g)(x)=4x+3

Step-by-step explanation:

Given the functions f and g defined above, their sum f+g is defined by (f+g)(x)=f(x)+g(x). Using algebra, we thus have (f+g)(x)=2x-1+2x+4=4x+3.

What is the length of each leg of the triangle below?

timama [110]

Answer:

A. 15

Step-by-step explanation:

Hypotenuse = 22

Since the two angles other than the 90° are both

45° , it means that the two legs of the right triangle are of equal length.

So, (x)²+ (x)² = 22²

2x² = 22²

x² = 484/2

x² = 242

x = √242

x = 15.55

x ≈ 15
