<h3>
Answer: C. x+9</h3>
===============================================
Explanation:
Think of two numbers that multiply to -36 and also add to 5. Put another way: think of two factors of -36 that add to 5.
Those two numbers are 9 and -4 since
9 times -4 = -36
9 plus -4 = 5
So we have x^2 + 5x - 36 factor into (x+9)(x-4)
x+9 is one factor
x-4 is the other factor

Alternatively, you can use a graphing tool to locate the x intercepts, and that will in turn lead to the factorization. Or you could use the quadratic formula to get the job done. Completing the square is yet another tool to use. So there are multiple approaches.

The value of x in the trapezoid given, to the nearest tenth, is: 10.5.
<h3>What is a Trapezoid?</h3>
A trapezoid is a quadrilateral that has two sides only that are parallel to each other.
<h3>What is the Area of a Trapezoid?</h3>
To find the area of a trapezoid, the formula used is expressed as: 1/2(a + b) × h, where:
- a and b are length of the two base sides that are parallel.
- h is the height of altitude of the trapezoid.
Given the following:
Area of trapezoid = 174 units²
AP = 6
PB = x + 3
CD = 2x + 6
AC = 10
Using the formula, we variables in the formula are:
a = AP + PB = 6 + x + 3 = x + 9
b = CD = 2x + 3
h = PC = √(AC² - AP²)
h = √(10² - 6²) = 8
Plug in the values into 1/2(a + b) × h:
174 = 1/2(x + 9 + 2x + 3) × 8
174 = 1/2(3x + 12) × 8
174 = (3x + 12) × 4
174 = 12x + 48
174 - 48 = 12x
126 = 12x
126/12 = x
10.5 = x
x = 10.5

Answer:
We are given a triangle having vertex at point M.
The base of the triangle is MN which is 3 units long.
Now, the height of the triangle is given as 5 units.
So, plotting a line starting at M, which is 5 units long towards the left or right will give us the height of the triangle.
Moreover, as the base is 3 units long.
We will have that the point N is 3 units down or up from the point M.
Using Pythagoras theorem, get that the length of the third side is 5.8 units.
After joining these points and constructing straight lines, we will get the following right angles triangle having base 3 units and height 5 units.
