       2b                     2a
----------------- +  -----------------
   (b+a)^2            (b^2 - a^2)

            2b                     2a
= ----------------- +  -------------------
      (b+a)(b+a)         (b+a)(b-a)

         2b(b - a) +  2a(b + a)
= ------------------------------------
           (b+a)(b+a)(b-a)


         2b^2 - 2ab  +  2ab + 2a^2
= ---------------------------------------
           (b+a)(b+a)(b-a)

         2b^2 + 2a^2
= ------------------------
        (b+a)(b+a)(b-a)

         2(b^2 + a^2)
= ------------------------
        (b+a)^2 (b-a)

Answer:

Numerator:        2(b^2 + a^2)
Denominator:    (b+a)^2 (b-a)

A sphere has a radius of 2x + 5. Which polynomial in standard form best describes the total surface area of the sphere? Use the
faust18 [17]
Start with the given formula for the surface area of a sphere.

S = 4 \pi r^2

Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.

S = 4 \pi (2x + 5)^2

S = 4 \pi (4x^2 + 20x + 25)

S = 16 \pi x^2 + 80 \pi x + 100 \pi

(3-0/4a)-(10-0.8a). Solve for a
torisob [31]

An equation is formed of two equal expressions. The value of 'a' in the given equation is 6.452.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The given equation can be solved for 'a' as shown below,

\dfrac{(3-0)}{4a} = (10-0.8a)\\\\\dfrac{3}{4a} = (10-0.8a)\\\\

0.75a = 10 - 0.8a

0.75a + 0.8a = 10

1.55a = 10

a = 6.452

Hence, the value of 'a' in the given equation is 6.452.
