Step-by-step explanation:
Answer:
4 3/8 inches.
Step-by-step explanation:
That is 7/8 * 5
= 7*5 / 8
= 35/8
= 4 3/8 inches of ribbon.
Answer:
The length of the shortest side of the triangle is 10 units.
Step-by-step explanation:
Let <em>a</em> be the shortest side of the isosceles triangle and <em>b</em> be the two congruent sides.
The congruent sides <em>b</em> are each one unit longer than the shortest side. Hence:

The perimeter of the isosceles triangle is given by:

This is equivalent to the perimeter of a square whose side lengths are two units shorter than the shortest side of the triangle. Let the side length of the square be <em>s</em>. Hence:

The perimeter of the square is:

Since the two perimeters are equivalent:

Substitute for <em>b: </em>
<em />
<em />
Solve for <em>a</em>. Distribute:

Simplify:

Hence:

The length of the shortest side of the triangle is 10 units.
There is no solution. if you are using the two equations to solve for y and x.
you can plug one equations into the other.
substituting one of the y gives...
3(x+4)=3(x-4)
÷ both sides by 3 gives x+4=x-4
get x on one side and numbers on the other
x-x =4+4
and x-x will give you a 0 for the left side
therefore 0 = 4+4.. not true.
