Answer:
43
Step-by-step explanation:
angle sum property of quadrilateral
87+ 103 + 127+ x = 360
317 + x = 360
x= 360-317
x = 43
he spent 27 now he has none, so if you add back how much he spent to what he has then you have what he had, which is 27
Answer:
11 degress celcius
Step-by-step explanation:
there was an original 5 but it increased by 6
5 + 6 = 11
11 degrees celcuis
The polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).
<h3>What is the
Area of a Trapezoid?</h3>
Area of trapezoid = 1/2(a + b)h, where a and b are length of the parallel sides, and h is the height.
Given:
a = 3x + 5
b = x - 2
h = 2x - 5
Thus:
Area of trapezoid = 1/2(3x + 5 + x - 2)(2x - 5)
Area of trapezoid = 1/2(4x + 3)(2x - 5)
Area of trapezoid = 1/2(8x² - 14x - 15)
Therefore, the polynomial that represents the area of the trapezoid shaped window is: 1/2(8x² - 14x - 15).
