(2m+7)-(3-4m) Please explain how to solve.

Step-by-step explanation:

The first step is to solve the parenthesis:

Now we put together similar terms:

We have and since the coefficients and are multiples of 2, We can factor a 2 from the equation, wich will give us the following:

The answer is

u dumb boi

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
