Hello from MrBillDoesMath!

Answer:

(r + s) * sqrt(t)

Discussion:

r*sqrt(t) + s * sqrt(t)                 => factor "sqrt(t)" out of each term

(r + s) * sqrt(t)

Thank you,

MrB

Brainlist to whoever shows me how to solve this step by step.
Andrews [41]

Answer:

  x ∈ {-4, 2}

Step-by-step explanation:

The x-coefficient (+2) is the sum of the constants in the binomial factors of the equation, and the constant term (-8) is their product.

Since you're familiar with the divisors of 8, you know that the two factors of -8 that total +2 are -2 and +4. These are the constants in the binomial factors:

  f(x) = x^2 +2x -8

  f(x) = (x -2)(x +4)

The roots of f(x) are the values of x that make these factors be zero. They are x=2 and x=-4.

The roots of f(x) are -4 and 2.

_____

Above is the solution by factoring. We can also "complete the square" to find the roots. Anytime we're looking for roots, we want the values of x that make f(x) = 0.

  x^2 +2x -8 = 0

  x^2 +2x = 8 . . . . . add the opposite of the constant

  x^2 +2x +1 = 8 +1 . . . . . add the square of half the x-coefficient: (2/2)² = 1

  (x +1)² = 9 . . . . . . . . . . . write as squares

  x +1 = ±√9 = ±3 . . . . . . take the square root

  x = -1 ± 3 . . . . . . . . . . . subtract 1

The roots are x=-4, x=2.

Grace has a 15 inch diameter bicycle tire. How many revolutions will it make traveling 500 feet?
Brums [2.3K]

Answer:

Revolution = 127.24 revolutions

Step-by-step explanation:

<em><u>Circumference of the tire = πD</u></em>

Where D = 15 inch

So,

C = 15π = 47.1 inch

<u><em>In feets:</em></u>

47.1 inch = 3.93 feet.

So, <u>one revolution = 3.93 feet</u>

<u><em>Travelling 500 feet will make the following revolutions:</em></u>

Revolution = 500 feet/3.93 feet

Revolution = 127.24 revolutions
