Answer:
Step-by-step explanation:
If they were joined together, wouldn't the length of both squares combined be 20cm?
Therefore, it'd be (10+20+10+20) for the perimeter.
60cm.
Answer:
The answer is a= 
Step-by-step explanation:
Combine like terms and we get,
divide both sides of the equation by ax, and simplify further,
notice that we can reduce the 24 over 6 1/2,
distribute and simplify further
And a=
Answer:
distribute,
Step-by-step explanation:
8+12+1 3/5x=-12
20+1 3/5x=-12
1 3/5x=8
x=5
The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)
<h3>What inequality represents the figure</h3>
In accordance with the figure, we have an inequation of the form y ≥ f(x). Now we proceed to find the <em>quadratic</em> equation of the parabola:
f(x) = a · (x + 1) · (x - 9)
- 125 = a · (4 + 1) · (4 - 9)
- 125 = a · 5 · (- 5)
- 125 = - 25 · a
a = - 5
f(x) = 5 · (x + 1) · (x - 9)
f(x) = 5 · (x² - 8 · x - 9)
f(x) = 5 · x² - 40 · x - 45
The figure is represented by the inequality y ≥ 5 · x² - 40 · x - 45. (Correct choice: C)
