Answer:
12
Step-by-step explanation:
x^2-2x+4 replace -2 for x
-2^2-2(-2)+4
4+4+4
12
The answer is 2/5, which is 2 over 5
Yes
Reason - figure b has been increased by 3 (x3 for each side)
Eg. figure b - 1. Figure a - 3
B)66.5in^2
The square is 49in^2 and the triangle has side lengths of 5 and 7 so the area is (5*7/2=17.5)
49+17.5=66.5
Answer:
1.234 / 100 = 0.01234
Therefore;
0.01234 x purchase price = profit
same as
purchase price / 1.01234 = profit
formula Cost or initial Price x ( % / 100 )
and show % as a whole number ie ) 1.234 / 100 = 0.01234
= cip x 1.01234 = profit
When we divide by 100 the 1 moves two spaces to the right.
when we have to find initial price from given sale price
we deduct given percentage from 100% and use that to multiply with instead omitting the 1 if its depreciating or adding the 1 if its original price ticket.
