Answer:
- 9x² - 36x - 27
Step-by-step explanation:
9 - (3x + 6)² ← expand using FOIL
= 9 - (9x² + 36x + 36) ← distribute parenthesis by - 1
= 9 - 9x² - 36x - 36
= - 9x² - 36x - 27
So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters

Cross Multiply
0.0075x = 0.48
x = 64 meters

Answer: 50</h3>
"deci" means tenth, so "decimeter" means "tenth of a meter"
0.10 meter = 1 decimeter
1 meter = 10 decimeters (multiply both sides by 10)
5 meters = 50 decimeters (multiply both sides by 5)

Answer:
The answer to your question is Triangle's area = 520 in², Square's area = 576 in²
Step-by-step explanation:
Process
1.- Calculate the area of the triangle
-Find the length of the base using the Pythagorean theorem
c² = a² + b²
-Solve for b²
b² = c² - a²
-Substitution
b² = 37² - 35²
-Simplification
b² = 1369 - 1225
b² = 144
b = 12 in
-Find the base
base = 2(12) = 24 in
-Find the area of the triangle
Area = base x height / 2
-Substitution
Area = 24 x 35 / 2
-Simplification
Area = 420 in²
2.- Find the area of the square
Area = side x side
-Substitution
Area = 24 x 24
-Result
Area = 576 in²
