Mathematics

Answer:

Step-by-step explanation:

Let the length b y

Width = 2x - 3

Perimeter = 18x + 4

And

Perimeter = 2(l + w)

18x + 4 = 2(y + 2x - 3)

Dividing through by 2

9x + 2 = y + 2x - 3

Making y as subject

y = 9x - 2x + 2 + 3

y = 7x + 5

The missing side is 7x + 5

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?
UNO [17]

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

1\frac{2}{3} × 3

1\frac{2}{3} can be rewritten as \frac{5}{3}, so:

\frac{5}{3} × \frac{3}{1}

= \frac{15}{3}

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!
