If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?
OlgaM077 [116]

Let's see what to do buddy...

____________________________

Reminder:

(a + b)(a - b) =  {a}^{2} -  {b}^{2}

So we need to just Multiply above equations like this :

x + y = 70

x - y = 40

(x + y)(x - y) = 70 \times 40

{x}^{2} -  {y}^{2} = 2800

____________________________

And we're done.

Thanks for watching buddy good luck.

The curved part of this figure is a semicircle.
Nitella [24]
Draw the diameter from point (-1, -5) to point (2, 3).

The triangle has base 3 and height 8.

The diameter of the semicircle is the hypotenuse of the triangle.

d = \sqrt{3^2 + 8^2}

d \approx 8.544

The radius is half the diameter.

r = \dfrac{d}{2} = \dfrac{8.544}{2} = 4.272

The total area is the area of the triangle plus the area of the semicircle.

A = \dfrac{bh}{2} + \dfrac{\pi r^2}{2}

A = \dfrac{3 \times 8}{2} + \dfrac{\pi \times 4.272^2}{2}

A = 12 + 9.125 \pi units^2
