Answer: 152.46 squared centimeters.

Step-by-step explanation:

The equation to find the area of the trapezoid is A = ½ (6.6 + 16.5) 13.2
Distribute ½ into (6.6 + 16.5) . A = (3.3 + 8.25) 13.2.
Add the numbers inside the parenthesis. A = 11.55 * 13.2
Multiply 11.55 * 13.2. A = 152.46.

Hey can you please help me posted picture of question

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:

$x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a}$

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15

Using the values, we get:
$x= \frac{11+- \sqrt{121-4(2)(15)} }{2(2)} \\ \\ 
x= \frac{11+-1}{4} \\ \\ 
x=3, x= 2.5$

So, the correct answer to this question are option B and D

Answer:

Step-by-step explanation:

The sum of angles in a quadrilateral is 360°.

  75° +125° +∠T +60° = 360°

  ∠T = 360° -260° = 100°

The true statement about these graph is that: B. the graph of the original function (y = 8/5x + 4) is perpendicular to the graph of the new function (y =- 5/8x + 8).

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to for the graphical representation of data on both the horizontal and vertical lines of a Cartesian coordinate, which are typically known as the x-axis and y-axis respectively.

<h3>How to interpret the graph?</h3>

Mathematically, the standard form of the equation of a straight line on a graph is given by;

y = mx + c

<u>Where:</u>

x and y are the points.

m is the slope.

c is the intercept.

<h3>The condition for perpendicularity.</h3>

In Mathematics, the condition for perpendicularity of two (2) lines is as follows:

m₁ × m₂ = -1

8/5 × (-5/8) = -1

Based on the graph (see attachment) of the original function and new function, we can infer and logically deduce that the true statement about their graph is that the graph of the original function (y = 8/5x + 4) is perpendicular to the graph of the new function (y =- 5/8x + 8).
