A(x) = (11+x)(7+3x)
A(x) = 77 + 33x + 7x + 3x^2
A(x) = x^2 + 40x + 77

Segment FG begins at point F(-2, 4) and ends at point G(-2, -3). The segment is translated 3 units left and 2 units up, then ref

Alexus [3.1K]

Answer:

$F'G' = 7$

Step-by-step explanation:

Given

$F = (-2,4)$

$G = (-2,-3)$

Required

Distance of F'G'

The transformation that give rise to F'G' from FG are:

Translation
Reflection

The above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.

i.e.

$F'G' = FG$

Calculating FG, we have:

$FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

Where:

$F = (-2,4)$ --- $(x_1,y_1)$

$G = (-2,-3)$ --- $(x_2,y_2)$

$FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}$

$FG = \sqrt{(0)^2 + (7)^2}$

$FG = \sqrt{0 + 49}$

$FG = \sqrt{49}$

Take positive square root

$FG = 7$

Recall that:

$F'G' = FG$

$F'G' = 7$

Determine the area. Show your work. Round your answer to the nearest hundredth

vlabodo [156]

Answer:

54

Step-by-step explanation:

To solve this, you have to find the area of the square then the area of the triangle, and add them together.

To find the are of a square you multiply the base by the height.

Example: 6 × 6 = 36

To find the area of a triangle you multiply the base by the height and divide it by 2.

Example: 6 × 6 = 36

36 ÷ 2 = 18

Now we add both areas together.

Example: 36 + 18 = 54
