Answer:
QT=4x+1, SV = 9x-4
Step-by-step explanation:
For QT:
1) segments RT and RV have the same length
2) segments QT and QV both start at point Q and end at opposite ends of segment TV which is perpendicular to segment QS
so the length of QV is equal to the length of QS
For SV:
1) segments RT and RV have the same length
2) segments ST and SV both start at point S and end at opposite ends of segment TV which is perpendicular to segment QS
so the length of SV is equal to the length of ST

EXPLANATION
The area of the square coaster is represented by:
We split the middle term to obtain,
We factor by grouping to get,
Since area of a square is l² , it means the side length of the square is
b) The perimeter of a square is given by
We substitute the length in terms of d, to obtain;
Or
Answer:
3 mph
Step-by-step explanation:
Let c represent the current of the river in miles per hour. Then the ratio of speed downstream to speed upstream is ...
(21 +c)/(21 -c) = 2.4/1.8
1.8(21 +c) = 2.4(21 -c) . . . . . . multiply by 1.8(21-c)
37.8 + 1.8c = 50.4 -2.4c . . . . eliminate parentheses
4.2c = 12.6 . . . . . . . . . . . . . . . add 2.4c-37.8
c = 3 . . . . . . . . . . . . . . . . . . . .divide by 4.2
The current of the river is 3 miles per hour.
