Answer:

Yes it is.

Step-by-step explanation:

Answer:

4b+8 = 20

---------------

4b = 20

-------------------

b = 5

Step-by-step explanation:

We need to solve for b in the following equation:

\frac{4b + 8}{2}  = 10

When we multiply each term by 2 the denominator cancels out:

\displaystyle 2 \times \frac{4b + 8}{2}  = 10 \times 2\\\\4b + 8 = 20

Next, we subtract 8:

4b +8 - 8 = 20 - 8\\4b = 20

Final step, we isolate the variable. We cancel the multiplication on the left side when dividing by 4 on each term

\displaystyle 4b = 20\\\\\frac{4b}{4} = \frac{20}{4}\\\\b = 5

We'll use the Pythagorean Theorem
130^2 = side^2 +50^2
side ^ 2 = 16,900 -2,500
side ^ 2 = 14,400
side = square root (14,400)
side = 120 feet
