widest to narrowest: y=3/2x2, y= -1/2x2, y= 1/4x2
The answer to your question is 8*5*4.
8*5=40
40*4=160 8 is twice of 4. the length is twice the width.
N= P-180. so the computer would originally be 720 dollars. reduced by 25%, or 180, the new price is 540.
1/5( 5/2 x 4/7 -11/7) + 3/28
Multiply the terms (5/2 x 4/7) in bracket then subtract it from 11/14. Result will be 10/7.
Then multiply 1/5 with 10/7. The result will be 2/7.
2/7 + 3/28 = 11/28
