You can solve this easily by using Pascal's Triangle (look that up if need be).
Here are the first four rows of P. Triangle:
1
1 1
1 2 1
1 3 3 1
example: expand (a+b)^3.
Look at the 4th row. Borrow and use those coefficients:
1a^3 + 3 a^2b + 3ab^2 + b^3
Now expand (4x+3y)^3:
1(4x)^3 + 3(4x)^2(3y) + 3(4x)*(3y)^2 + (3y)^3
Look at the 2nd term (above):
3(4x)^2(3y) can be re-written as 144x^2y.
The coeff of the 2nd term is 144. Note that (4)^2 = 16
The answer is 0.3 thanks for the points
Answer:
Step-by-step explanation:
Ur answer should be B
Answer:
$285
Step-by-step explanation:
<u>Blueberries:</u>
B = number of pounds of blueberries bought
$5.50 = price of blueberries per pound
$5.50B = total price of B pounds of blueberries
<u>Blueberries:</u>
R = number of pounds of raspberries bought
$4 = price of raspberries per pound
$4R = total price of R pounds of raspberries
<u>Total:</u>
$5.5B + $4R
Since 5.5B+4R=285, then Amit spends in total on both types of berries $285
