➷ Just work with what is inside the parenthesis
Also, move around the terms to help it make more sense:
(cosA cosB - cosA cosB + sinA sinB + sinA sinB)
As you can see, the 'cosA cosB' would cancel out through subtraction.
Now we have this:
(sinA sinB + sinA sinB)
This is just two sets of sinA sinB so it can be written as:
(2 * sinA sinB)
Simply place the values outside the parenthesis back there to get the answer
SinA sinB = 1/2 * (2 * sinA sinB)

It's just like multiplying and dividing a negative, such as -1 *2=-2 and -2 / 1= -1
if there is one negative then it will be negative, so in this case it will be -7 / 2=
answer= -3 1/2

Answer:
The original price was 36.40
Step-by-step explanation:
p = original price of cake
using the coupon
p - 15% off = 30.94
p - .15 p = 30.94
Combine like terms
.85p = 30.94
divide each side by .85
p = 30.94/.85
p =36.40
The original price was 36.40
