The largest side of a triangle is six more units than the smallest side. The third side is twice the smallest side. If the perim eter of the triangle is 25 units, write and solve an equation to find the lengths of all three sides of the triangle.
1 answer:
Equation: x + x + 6 = 2x = 25 smallest side is 4.75 units largest size is 4.75 + 6 = 10.75 units 3rd side is 2(4.75)= 9.5 units smallest side is x largest size is x + 6 3rd side is 2x ----------------------------------- 4x + 6 = 25 -6 -6 <u>4x</u> = <span><u>19</u> </span> 4 4 x = 4.75 is the smallest side smallest side is 4.75 units largest size is 4.75 + 6 = 10.75 units 3rd side is 2(4.75)= 9.5 units

The answer is C just did all the work
It will take 4 hours, this is because it said it adds 1000 after two hours, and it will add another 1000 two hours later which will give you your answer of four hours
