Answer:
Solution:
Step 1: Remove parentheses by multiplying factors.
= (x * x) + (1 * x) + (2 * x) + (2 * 1)
Step 2: Combine like terms by adding coefficients.
(x * x) = x2
(1 * x) = 1x
(2* x) = 2x
Step 3: Combine the constants.
(2 * 1) = 2
Step 4: Therefore, Simplifying Algebraic Expression is solved as
= x2 + 3x + 2.

Answer:
Explanation:
<u>Description of triangle EFD</u>:
- Angle EFD: right angle (90º)
- x: adjacent leg to angle EDF
- 3: hypotenuse of triangle EFD
<u>Description of triangle EDG</u>:
- Angle EDG: right angle (90º)
- 4 adjacent leg to angle EGD
- 5: hypotenuse of triangle EDG
<u>Similarity</u>:
- Triangle EFD and triangle EGD are similar.
Then, since corresponding parts of similar triangles are proportional:
<u>Clear x</u>:
