Answer: 9210
Step-by-step explanation:
Answer:
The answer is 37 200.
Step-by-step explanation:
The steps are :
x² - y² = (x + y)(x - y)
193² - 7² = (193 + 7)(193 - 7)
= (200)(186)
= 37 200
You can graph the points and see if they fall in a straight line. After doing this, you'd be able to see that all the lines fall in the same line. This means that the points in the table are linear.<span />
Answer: 20/3
Solution:
-5^2/-15 + 5
Determine the sign
5^2/15 + 5
Calculate
25/15 + 5
Simplify
5/3 + 5
Transform the expression
5 + 15/3
Calculate
= 20/3
(But there’s alternative forms too!: 6.6, 6 2/3)
Each one is multiplied by -2...
PROOF
-5 * 10 = -20
-20 * -2 = 40
And so on.
So we need two more numbers so do 40 * -2...
40 * -2 = -80
And then...
-80 * -2 = 160
So the first 6 numbers are...
-5, 10, -20, 40, -80, 160.
We need to find the SUM, which is all the numbers added together.
-5 + 10 - 20 + 40 - 80 + 160 = 105
105 is your answer.
