Answer:

a = 0

Step-by-step explanation:

a + 5 = -5a + 5 subtract 5 from both sides

a + 5 - 5 = -5a + 5 - 5

a = -5a add 5a to both sides

a + 5a = -5a + 5a

6a = 0 divide both sides by 6

6a / 6 = 0 / 6

therefore,

a = 0

Solve the equation we have that:

a. S = 3V²/ 4

b. S = 108 feet

<h3>How to solve the parameters?</h3>

We have the equation to be;

V = 2√3S

Where;

V is the speed
S is the length

Let's make S the subject from the formula, divide both sides by 2√2S = v/ 2. Take square of both sides:

$(\sqrt{3S} )^2 = \frac{V^2}{4}\\3S = \frac{V^2}{4}$

Now we need to divide both sides by three:

S = 3V²/ 4

b. If v = 12miles per hour, substituting in the equation found earlier:

S = 3 (12²)/ 4

S= 432/ 4

S = 108 feet

Thus, the formula for the length is S = 3V²/ 4

Answer:

Isosceles Right Triangle

Step-by-step explanation:

We look at the sides first. Two sides are equal, which means that the triangle is isosceles (equilateral means three equal sides, and scalene means no sides equal). Then we look at the only angle indicated, which is the right angle. Thus, we come to the conclusion that the triangle is an Isosceles Right Triangle.
