Answer:
√17 or 4.12 inches
Step-by-step explanation:
√9²-8²=√81-64=√17 inches
or 4.12 inches
A
I believe that I am correct
The m in the equation is the slope and the y-intercept is the b.
y=1x-1
y=mx+b
3y-12=-30
3y=-30+12
3y=-18
y=-18/3
y=-6.
Answer: A.
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.
