<h3>Answer is   4:7</h3>

Explanation:

There are 20 yellow triangles and 15+20 = 35 triangles total.

The ratio of yellow to total is 20:35. The order is important.

We divide both parts by the GCF 5 to get the reduced ratio 4:7

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x² + 1

g(x) = x² - 5

(f + g)(x) is f(x) + g(x)

<u>Step 2: Find (f + g)(x)</u>

  1. Substitute:                    (f + g)(x) = 4x² + 1 + x² - 5
  2. Combine like terms:    (f + g)(x) = 5x² - 4
