(m-3)/(7)=(m)/(m+8) Solve the proportion.

ExtremeBDS [4]

Answer: m=6, m=-4

Step-by-step explanation:

To solve this proportion, we have to cross multiply.

$\frac{m-3}{7} =\frac{m}{m+8}$

$(m-3)(m+8)=7m$

Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.

$m^2+8m-3m-24=7m$

Combine like terms.

$m^2+5m-24=7m$

We can move all terms to one side and then solve for m.

$m^2-2m-24=0$

We can actually factor this to:

$(m-6)(m+4)=0$

We set each factor equal to 0 to find m.

m-6=0

m=6

m+4=0

m=-4

Step-by-step explanation:

Here, we want to express the given equation in the following form;

So we can have this as;

5x-4y-20 = 0

That means we have;

a as 5

b as -4

1. What is the simplest form of the radical expression? 4 fourth root of two x+ 6 fourth root of two x (1 point) 10fourth root o

iragen [17]

Your expression is:
4·⁴√(2x) + 6·⁴<span>√(2x)

As you can see, the radicals are exactly the same: same index, same radicand.

Therefore you can treat it as if it was:
4 apples + 6 apples
which is 10 apples,

or in your case:
10</span>·⁴√(2x)

Hence, the correct answer is option A.
