Is the solution shown below correct? Explain.
9x+2=8x2+6x
Negative 8 x squared + 3 x + 2 = 0. x = StartFraction negative 3 plus-or-minus StartRoot (3) squared minus (4) (negative 8) (2) EndRoot Over negative 16 EndFraction. x = StartFraction negative 3 plus-or-minus StartRoot 9 minus (64) EndRoot Over negative 16 EndFraction. x = StartFraction 3 plus-or-minus StartRoot 55 Endroot i Over 16 EndFraction.

Stefano accidentally dropped his sunglasses off the edge of a canyon as he was looking down. the height, h(t), in meters (as it relates to sea level), of the sunglasses after t seconds, is shown in the table. during its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber? 166 meters 176 meters 230 meters 240 meters its b.176 i took the test 166 is wrong and 176 is correct

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'
