We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:


This is, indeed correct, thus, this

a right triangle.</em>
Answer:
D
Step-by-step explanation:
Answer:
1,772 cm²
Step-by-step explanation:
To find the answer
Area of the rectangle - Area of 2 circle inside
= Shaded Area
(40 x 60) - (2 x π x 10²) = 1,772 cm²
Here, x - 2y = 14
x = 14 + 2y
Now, substitute this value into first equation,
4x + 6y = 0
4(14 + 2y) + 6y = 0
56 + 8y + 6y = 0
14y = -56
y = -56/14
y = -4
Substitute it into second equation,
x = 14 + 2(-4)
x = 14 - 8
x = 6
In short, Your Answer would be: (6, -4)
Hope this helps!
