Answer:
Option D: CE, ED, CD
Step-by-step explanation:
In a right triangle, the hypotenuse is always the longest side. Therefore, "CE, ED, CD" is the correct option.
Answer:
[-20.25;+∞).
Step-by-step explanation:
1) according to the properties of the given parabola the minimum is:
2) y₀=-20.25 means, the value -20.25 is minimum of the range, the maximum →+∞;
3) finally, the range y≥-20.25.
<em>B) 3.6x - 4.8</em>
- Step-by-step explanation:
<em>Hi there !</em>
<em>0.3(12x – 16) =</em>
<em>= 0.3×12x - 0.3×16</em>
<em>= 3/10×12x - 3/10×16</em>
<em>= 36x/10 - 48/10</em>
<em>= 3.6x - 4.8</em>
<em>Good luck !</em>
Answer:
x = 9 ; 39 in. ; 156 in.
Step-by-step explanation:
Because it is a square, we know that all 4 sides are equal to each other.
This means we can take the two expressions and equal them to each other.
4x + 3 = 3(2x - 5)
4x + 3 = 6x - 15
-2x + 3 = -15
-2x = -18
x = 9
Now that we know the value of x, we can substitute it in to find the side length.
4(9) + 3
36 + 3
39 in.
Therefore, each side of the square is 39 in.
Finally, since we know all the side lengths are 39, we can find the perimeter by adding up all 4 side lengths.
p = 4(39) = 156 in.
Therefore, the perimeter of the square is 156 in.
