Answer:
136
Step-by-step explanation:
Area of top and bottom added together:
(6) (7) + (6) (7)
42 + 42
<u>84</u>
Area of front and back added together:
(7) (2) + (7) (2)
14 + 14
<u>28</u>
Area of left and right added together:
(2) (6) + (2) (6)
12 + 12
<u>24</u>
Add all underlined numbers:
Area of top and bottom + Area of front and back + Area of left and right
84 + 28 + 24
136
So the slope is 5 and you know the points, (0,4)
y-4=5(x-0)
y-4 = 5x
y = 5x + 4 is the slope intercept form
standard form is: -5x + y = 4 OR y - 5x = 4
B) obtuse triangle
Hope this helps!
By the Pythagorean theorem,
.. x^2 +(x -46)^2 = (x +4)^2
.. 2x^2 -92x +2116 = x^2 +8x +16
.. x^2 -100x +2100 = 0
.. (x -50)^2 -400 = 0
.. x = 50 ±20 . . . . . only x=70 makes any sense in the problem
The height, x, of the tree is 70 meters.
The side of the square has a measurement given as 3^5/2. We calculate the area using the equation A = s². We calculate as follows:
A = (3^5/2)^2
A = (3^5)
A = 243 in²
Hope this answers the question. Have a nice day.
