Notice the tickmark on the angles, those angles are equal to each other.

now, notice the angle at the very top, the large triangle is really sharing it with smaller-inscribed triangle, and therefore is equal on both triangles.

therefore, the larger triangle, is similar with smaller-inscribed triangle by AA.

what the dickens does that mean?

\bf \cfrac{large}{small}\qquad \cfrac{4+5}{4}=\cfrac{5+x}{5}\implies \cfrac{9}{4}=\cfrac{5+x}{5}\implies 45=20+4x
\\\\\\
25=4x\implies \cfrac{25}{4}=x\implies 6\frac{1}{4}=x

Drag the factors to the correct locations on the image. Not all factors will be used.What is the factored form of this expressio
Afina-wow [57]

(3m+5n)(9m²-15mn+25n²)

1) Let's factorize 27m³ +125n³.

27m³ +125n³ <em>Let's use x³ +y³ product to factorize that</em>

<em />

x³ +y³ = (x +y)(x²-xy +y²)

2) So let's rewrite it, since 3³ = 27 and 5³ = 125

27m³ +125n³ =

Plug x =3m and y = 5n into those factors (x +y)(x²-xy +y²)

27m³ +125n³= (3m + 5n)(3²m² -5n*3m +5²n²)

27m³ +125n³= (3m+5n)(9m² - 15mn +25n²)

3) So the answer is

(3m+5n)(9m²-15mn+25n²)
