Answer:
10 units
Step-by-step explanation:
Let the shortest side be x
Now since we are given that The congruent sides of an isosceles triangle are each 1 unit longer than the length of the shortest side of the triangle.
So, the length of the congruent sides (each) = x+1
Thus the perimeter of triangle = sum of all sides
= x+x+1+x+1
=3x+2
Now we are given that The perimeter of the triangle is the same as the perimeter of a square whose side length is 2 units shorter than the length of the shortest side of the triangle.
Side of square = x-2
So, perimeter of square = 4*side
=4(x-2)
=4x-8
Now since the perimeter of the triangle and square are equal
So,

Hence the shortest side of the triangle is 10 units.
Ans: D

Answer:
It will take 8 hours for the 5 workers to complete the same job.
Step-by-step explanation:
The amount of work done is the same for both crews.
Work = time * workers
Work = 10 * 4
Work = time * 5
Set the two equal
10 * 4 = time * 5
Divide each side of the equation by 5
10*4/5 = time *5/5
8 = time
Answer:

Step-by-step explanation:
We look for where
. The way you find the answer is first, find the point
. Draw a line straight up and down, and see where that line intersects the function. Those intersection points are your answer(there will always be only 1 for a function, but if a graph isn't a function, there might be more than 1).
Using this method here, we see that
intersects our line at
, so
.
