for A multiply 85 and 30. then subtract 30 by the product, this gives you the sale price. For B you do the same thing but you multiply 18 and 85. then 18 subtracted by the product which gives you the sale price.
Set up a proportion
42.50/5=x/8
5x=340
x=68
He would earn $68
Answer is no solution I believe
You can divide the polygon into a triangle (VMR) and rectangle(VEDR)
VE=5
VR=6
The area for VEDR would be:
area= VE*VR= 5*6= 30
triangle height=3
VR=6
The area for VMR
area= 1/2 * 3 * 6= 9
Total area= 30 + 9 = 39
ANSWER
EXPLANATION
The given binomial expansion is:
Compare this to
we have a=2x , b=-3y and n=10
We want to find the coefficient of the term
This implies that, r=5.
The terms in the expansion can be obtained using
We substitute the given values to obtain;
Hence the coefficient is;
