A=pir²
64=pir²
divide both sides by pi
64/pi=r²
sqrt both sides

Write the quadratic equation in standard form:<br> 7x + 8 + 2x2<br> 2x + 1 + x2
JulsSmile [24]

Answer:

3x^2 + 9x  +9

Step-by-step explanation:

Given

(7x + 8 + 2x^2) + (2x + 1 + x^2)

Required

The result in standard form

We have:

(7x + 8 + 2x^2) + (2x + 1 + x^2)

Remove brackets

7x + 8 + 2x^2 + 2x + 1 + x^2

Collect like terms

7x+ 2x  + 8 + 1 + 2x^2+ x^2

9x  + 9+ 3x^2

The standard form of a quadratic equation is:

ax^2 + bx + c

So, we have:

9x  + 9+ 3x^2

3x^2 + 9x  +9
