Answer:
Step-by-step explanation:
The first choice is correct
The rate is 20 per dog, thus we get the equation:
c= 20d
However the first dog is free, so the equation becomes
c = 20(d - 1)
And he also has a walking fee of 85 dollars and thus the equation becomes
c= 85 + 20(d-1)
<u><em>Answer:</em></u>
Area of triangle = 12 units²
<u><em>Explanation:</em></u>
<u>Area of triangle is calculated using the following rule:</u>
Area = 0.5 * base * height
Now, in the given figure each square represents one unit, therefore, we will get the lengths by counting squares
Base = BC = 8 units
Height is the perpendicular distance from vertex A to the base BC = 3 units
<u>Substitute with these values in the above equation to get the area as follows:</u>
Area = 0.5 * 8 * 3 = 12 units²
Hope this helps :)
Answer:
perfect square trinomial methodIf a polynomial has three terms, x2 + 12x + 36, which factoring method can be considered? Summary: If a polynomial has three terms, x2 + 12x + 36, the perfect square trinomial method can be considered to find the factor of the expression.
Answer:
Two events are said to be dependent if the outcome or occurrence of the first affects the outcome or occurrence of the second so that the probability is changed.
Also, Two events are said to be independent if the outcome or occurrence of the first does not affects the outcome or occurrence of the second so that the probability is not changed.
