First you convert 20% into a decimal which is 0.2 and multiply that by 42 and you get 8.4, that's the discount. Then you subtract 8.4 from 42 and get $33.60 which is your answer. Hope this helps!!
Answer:
4,096
Step-by-step explanation:
It goes like this 4 * -4=-16, 16*4=64, -64*4=256, etc.
You use the sum of the last number but flip the sin to make it opposite like if your some was + make it a negative to get your next product. Hope that made sense!!!!
aApolynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
There are 3 sets of polynomials; LINEAR, QUADRATIC and CUBIC
Linear: 
Quadratic: 
Cubic: 
Because both of them are congruent triangles.
The have sides that equal to each other, angles that equal to each other and a common base.
I hope this helps you
Area of parallelogram =base×height
Area =87×18,6
Area =1618,2
