Answer:
a=0.5 in
b=1.14 in
c=3.74 in
Step-by-step explanation:
(3x-4)² is
(3x-4)(3x-4)
FOIL it.
9x²+3x-4+3x-4+16
simplify
9x²+6x+8
The system of equation is: 15x+12y=348, 8x+8y=200. The price of a jacket times number of jackets means the amount of money spent on jackets, and same for sweatpants. Their sum is the total amount of money spent.
First you set up the problem- 7/12=x/100. then you cross multiply 7×100=700 then divide 12 into 700 so 700÷12=58.333333333333 and so your percentage is 58.3%
I think it is always true. I am not sure but I hope I'm right
