Answer:

Step-by-step explanation:

The area of a rectangle = length × width

To find the width, divide the area by the length

width = $\frac{area}{length}$ = $\frac{3x^2+9x}{3x}$

To simplify divide each term on the numerator by 3x

= $\frac{3x^2}{3x}$ + $\frac{9x}{3x}$ = x + 3 ← width

Suppose that G(X) = F(x+ 9). Which statement best compares the graph of

coldgirl [10]

Answer: Option D

Step-by-step explanation:

By definition if we have a function F (x) and perform a transformation of the form

$G (x) = F (x + c)$

Then it is true that:

If c is negative the graph of G(x) will be equal to the graph of F(x) displaced horizontally c units to the right

If c is positive, the graph of G(x) will be equal to the graph of F(x) displaced horizontally c units to the left.

Note that in this case the transformation is:

$G (x) = F (x + 9)$

Then $c = 9$ and $c> 0$

Therefore the graph of G(x) will be equal to the graph of F(x) displaced horizontally <em>9 units to the left</em>

The answer is the option D.

What is the area , in square meters of the shaded part of the rectangle below

Licemer1 [7]

Answer:

123.5 m^2

Step-by-step explanation:

The area of the whole rectangle is 9 x 19 = 171 m^2

The area of the region that isn't shaded is (5 x 19)/2 = 47.5 m^2 because the height of the triangle is 5 (9 - 4) and the area of a triangle is

(height x length)/2

171 - 47.5 = 123.5 m^2
