What is the length of b
oksian1 [2.3K]

Answer:

b = 24

Step-by-step explanation:

<u>Concepts</u>

The Pythagorean Theorem states that the sum of the squares of the two other sides on a right triangle is equal to hypotenuse (longest side) squared. It can be represented by the equation a^2+b^2=c^2. We can also use this formula to solve for the other two legs in the right triangle.

<u>Application</u>

In this case, we're asked to find the length of b in the right triangle, given c as 26 and a as 10. Now, we just apply the formula and solve for b.

<u>Solution</u>

Step 1: Set up equation and simplify.

  • 10^2+b^2=26^2
  • 100+b^2=676

Step 2: Subtract 100 from both sides.

  • 100+b^2-100=676-100
  • b^2=576

Step 3: Take square root of both sides.

  • \sqrt{b^2} =\sqrt{576}
  • b=24

Therefore, b = 24.

Reduce fraction: a^3+a^2b/5a times 25/3b+3a
Margaret [11]

ANSWER

\frac{5a}{3}

EXPLANATION

The given fractions are:

\frac{{a}^{3}  +  {a}^{2} b}{5a}  \times  \frac{25}{3b + 3a}

We factor to obtain:

\frac{{a}^{2}(a  +   b)}{5a}  \times  \frac{25}{3(a + b)}

We cancel the common factors to get:

\frac{{a}(1)}{1}  \times  \frac{5}{3(1)}

We multiply the numerators and also multiply the denominators to get:

\frac{5a}{3}

Therefore the two fractions simplifies to \frac{5a}{3}
