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.

hazel prepared 6/8 liter os juice and 5/8 liter of guyabano juice.how many liters of juice did she prepare in all

SIZIF [17.4K]

Answer:

Step-by-step explanation:

i believe you just have to add the fractions together since the denominator are the same :)

$\frac{6}{8} + \frac{5}{8} = \frac{6 + 5}{8} = \frac{11}{8}$

So in total Hazel can produce $\frac{11}{8}$ Liters of juice
