= 1/2 ( x + 5 ) ( x + 4 )
Answer:
Area = 1.54
Step-by-step explanation:
Area = π
π = 3.14
diameter = 1.4
radius (half of diameter) = 0.7
Area = 3.14 x 
Area = 3.14 x 0.49
Area = 1.5386
round to the nearest hundredth:
1.5386 = 1.54
If the two triangles are congruent (not just similar), then QS and TV would be equal. Thus, 3v + 2 = 7v - 6.
Solving this equation for v: 4v = 8, and v = 2.
Then QS = 3(2) + 2, or 8, and TV should be the same: 7(2) - 6 = 8.
