Four friends went fishing and each caught 1 fish. the fish they caught weighed 138 lb, 1516 lb, 1710 lb, and 135 lb. what was the weight of the heaviest fish? a. 1710 lb b. 135 lb c.1516 lb d.138 lb asap pl

Well this is a quite straight forward question and there must be some mistake in it. You can find the answer by simply comparing them.

So there must be a mistake in the question. It might be of fractions or decimals or some thing else in order to make it at least a little complicated.

Other wise obviously the answer for this must be the fish with the weight 1710 lbs was the heaviest.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
