Answer:
(assuming you are knowledge about Pythagoras theorem)
44.205
Step-by-step explanation:
draw the altitude line to the upper right corner and the lower left corner and you have 2 identical right triangles and a rectangle. If you solve the third side of the right triangles you get 1.685 (sqrt[7.2^2 - 7^2]).
now add up the areas of both triangles and the rectangle in the center whose base is 4.63 (subtract the 3rd side from 8)
you have
1.685(7) + 7(4.63)

----------- =. 100^2= 10000

2x^2-7/2= x^2-7/2
x^2-7/2=10000
x^2 = 20007/7
Answer:
5_7=2 9_3=6. 5+7=12 9+3=12
Step-by-step explanation:
Let y directly proportional to X
thus y = CX
where c is proportionality constant
given c= 9
thus y = 9x
