Answer:

$A=\frac{B^3}{5g+m}$

Step-by-step explanation:

Step 1: Write out equation

5gA + mA = B³

Step 2: Factor out A

A(5g + m) = B³

Step 3: Divide both sides by 5g + m

$A=\frac{B^3}{5g+m}$

What are the solutions to the equation x^2-8x=24

Oduvanchick [21]

$x^{2} - 8x = 24$

Transposing the equation to give zero on the RHS:
$x^{2} - 8x - 24 = 0$

Since we can't factorise it directly, we must complete the square to yield any solutions:
$x^{2} - 8x + ( \frac{8}{2})^2 - (\frac{8}{2})^2 - 24 = 0$
$(x^{2} - 8x + 16) - 16 - 24 = 0$
$(x-4)^2 - 40 = 0$
$(x-4)^2 = 40$
$x-4 = +/- \sqrt{40}$ ––> because square rooting yields a positive and negative solution.
x = 4 +/- $\sqrt{40}$
x = 4 +/- $2 \sqrt{10}$

Correct me if I'm wrong anyone.

What are the coordinates of the midpoint of the line segment with endpoints J(−6, 3) and K(4, −2) ?

34kurt

Midpoint formula : (x1 + x2) / 2, (y1 + y2)/2
(-6,3)....x1 = -6 and y1 = 3
(4,-2)...x2 = 4 and y2 = -2
now sub
m = (-6 + 4) / 2, (3 - 2) / 2
m = (-2/2, 1/2)
m = (- 1, 0.5) <==
