Answer:it would be 15cm^2 I think
Step-by-step explanation:
Answer:
-226,981
Step-by-step explanation:
This is how you do it.
First, you do 3-2 which is 1.
Then, you do 3-4 to the 3rd power which is -61.
After, you do 1*-61 because there are parenthesis, which equals -61.
Then, you do -61, which is the total of everything in parenthesis, and do it times the power of 3 to get -226,981.
Hope it helps!!^_^
Answer:
They both factored it correctly
Step-by-step explanation:
To find the one that was factored correctly, we expand the two of them and compare with
.
Fernando

= 
= 
Salma

= 
= 
As we can see, they both factored it correctly.
The equation of line perpendicular to given line through (-6,7) is:

Further explanation:
Given equation of line is:

The co-efficient of x is the slope of given line.
Let m1 be the slope of given line
and
m2 be the slope of line perpendicular to given line
Then

Product of slopes of perpendicular lines is -1

The equation of new line can be written as:

Putting m2

To find the value of b, we will put (-6,7) in equation

Putting the values of b and m in general equation
