Answer:
<u>explanation</u>:
solving similarities:
bigger triangle is double of the smaller triangle.
<u>balancing them</u>:
→ x + 9 = 2(2x - 3)
→ x + 9 = 4x - 6
→ 4x - x = 9 + 6
→ 3x = 15
→ x = 5
Answer:Given that the area of the mojave desert is 25,000 square miles and a scale drawing of the mojave desert has an area of 10 square inches.
The scale of the map is given by
Therefore, the scale of the drawing is 50 : 1.
Step-by-step explanation:
Answer:
g(x) = x(x - 5)(x + 4)
Step-by-step explanation:
Here the binomial is x + 4, indicating that a root is -4. Note that x is common to all terms of g(x)=x3−x2−20x, so we can immediately write g(x) in partially factored form as
g(x) = x(x^2 - x - 20). Since -20 = -5*4,
g(x) = x(x - 5)(x + 4)
1/4 = 2/8... So:
3/8 - 2/8 = 1/8
