Step-by-step explanation:
- Pick two whole points on the graph
- Then, use this formula: Y2 - Y1
X2 - X1
- Finally, you're given a solution (slope)
Exponents inside the parentheses are done first
eg. 5 + (25- 2) = ?
You would do the numbers inside first
25-2=23 to get 5 + 23 = 28

Answer:
A. and D.
Step-by-step explanation:
To get the unit rate, you divide the y value by the x value.
180/15 = 12
The x value becomes a 1.
This means A. is correct.
Take the unit rate to find the profit for 20 scarves. To get 20, you multiply 1 by 20.
1 * 20 = 20
Do the same to 12.
12 * 20 = 240
This will give you the point (20, 240).
This means D. is correct.
In square based pyramid
Length of base (a)=6cm
Slant height (l)=4 cm
Now,
LSA=2al
= 2*6*4
=48cm^2
