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.

Together, teammates Pedro and Ricky got 2689 base hits last season. Pedro had 285 more hits than Ricky. How many hits did each p
STALIN [3.7K]
Pedro had 1487 hits
Ricky had 1202 hits

2688/2=1344.5
285/2=142.5
1344.5-142.5=1202 (Ricky)
1344.5+142.5=1487 (Pedro)
1487-1202=285
1487+1202=2689

Why do we use scientific notation, and what are the parts of an expression written in scientific notation?
kiruha [24]

Answer:

We use scientific notation as sometimes numbers are so so big, that it becomes inconvenient for us to write the actual number.

Step-by-step explanation:

For example, if you have 9 billion of something, you wouldn't want to write those 9 zeroes all the time.

When writing in scientific notation we count the number of decimal places to when we have one non-zero integer to the right of the decimal place. We then write that number and multiply it by ten to the number of decimal places you counted earlier.

e.g. 4.8 X 10^7
