Q4. The diagram shows a triangle inside a rectangle.
Yanka [14]

The prove to show that the area of the shaded portion is 18x  - 30 is as follows: 3x² + 13x - 30 - 3x² + 5x = 18x  - 30

<h3>How to find the area of the shaded region?</h3>

The area of the shaded region can be represented as follows:

area of the shaded region = area of rectangle - area of triangle

Therefore,

area of the rectangle = (x + 6)(3x - 5)

area of the rectangle = 3x² - 5x + 18x - 30

area of the rectangle = 3x² + 13x - 30

area of triangle = 1 / 2 × 2x × 3x - 5

area of triangle = 3x² - 5x

Therefore,

area of the shaded portion =  3x² + 13x - 30 - 3x² + 5x

area of the shaded portion = 18x  - 30

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)
