Answer:
Step-by-step explanation:
Let's apply the formula (x+y)² = x² + 2xy + y²
Here, x = -a and y = b
So,
= (-a)² + 2(-a)(b) + (b)²
= a² - 2ab + b²
Hence, it has been proved that (-a + b)² = a² - 2ab + b².

Answer:
7 - x = 20 hope this helps!!
Step-by-step explanation:
can Iget brainliest?? ;P
It’s -4 because when you take 4 out of 8 then you still have another 4 to take away to you go into the negatives and have the answer -4
For polynomials, if we say of "rate of change", we are talking about the slope of the tangent line. That is the value of dy/dx or the differential of y in terms of x. From the given choices, the answer would be the second choice, y = 19x - 10. This is because dy/dx in this item is essentially equal to 19 which is a constant.
The probability would be 8/12
