<span>You can use Heron's formula to solve this problem.
</span>

, where
A is the area;
a,b,с are the sides;
s<span> is the </span>semiperimeter<span> of the triangle
</span>

<span>According to conditions:
</span>a = x
b = x+1
с = 2x-1
<span>Calculate the semiperimeter:
</span>

<span>Now we can compose and solve the equation according to Heron's formula:
</span>

<span>As a result, x = 6 is your answer.
I hope this helped.</span>
Answer:
42 miles
Step-by-step explanation:
20 x 16.7 = 334 miles on a full tank of gas
he drove 292 miles so 334 - 292 = 42 miles left
(x, y) → (x, y + n) - translate the graph n units up
(x, y) → (x, y - n) - translate the graph n units down
(x, y) → (x - n, y) - translate the graph n units left
(x, y) → (x + n, y) - translate the graph n units right
---------------------------------------------------------------------------
(x, y) → (x + 2, y)
translate the graph 2 units right.
The perimeter of ADC is 9.5 cm.
Answer:
54/5
Step-by-step explanation:
5(x+10)-25=54+25
5x + 50 - 25 = 54 + 25
5x + 50 - 25 = 79
5x + 25 = 79
5x = 79 - 25
5x = 54
x = 54/5
