Analyze the diagram below and complete the instructions that follow. Find the value of x.
A. 18
B. 22
C. 24
D. 28

A

Step-by-step explanation:

Using Pythagoras' identity on the large right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

(x + 32)² = 30² + 40² = 900 + 1600 = 2500 ( take the square root of both sides)

x + 32 = = 50 ( subtract 32 from both sides )

x = 18 → A

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

homozygous. one is homozygous, while two is heterozygous.
