Answer:
( 6 4 − 1 3 − 8 ) − 1 ( 5 4 + 6 − 8 3 )
Step-by-step explanation:
Rearrange terms
( 6 4 − 1 3 − 8 ) − 1 ( 5 4 + 6 − 8 3 ) ( 6 4 − 1 3 − 8 ) − 1 ( 5 4 − 8 3 + 6 )
distribute
(6 4 − 1 3 − 8 ) − 1 ( 53 4 − 8 3 + 6 ) (6 4 − 1 3 − 8 ) − 5 4+ 8 3 − 6
Eliminate redundant parentheses
combine like terms
multiply like 1
solution: 4 + 7 3 − 1 4
9y⁴−9y
Subtract 8y48y4 from 5y45y4.
6y4−y−8y−(−3y4)6y4-y-8y-(-3y4)
Multiply −3-3 by −1-1.
6y4−y−8y+3y46y4-y-8y+3y4
Simplify by adding terms.
Add 6y46y4 and 3y43y4.
9y4−y−8y9y4-y-8y
Subtract 8y8y from −y-y.
x = 40.
The corresponding sides are in the same proportion so:
45/ 27 = 30/18 = x/24
Consider the last 2 fractions:
30/18 = x/24
5/3 = x/24 Cross multiply:
3x = 5 * 24
x = 120 / 3
