Solve the equation x2 – 10x – 8= 0 to the nearest tenth.

x = -0.8 and 10.8

Step-by-step explanation:

Given the equation x2 – 10x – 8= 0

Using the general formula

x = -b±√b²-4ac/2a

x = -(-10)±√(-10)²-4(1)(-8)/2(1)

x = 10±√100+32/2

x =10±√132/2

x = 10±11.489/2

x = 10-11.489/2 and 10+11.489/2

x = -1.489/2 and 21.489/2

x = -0.8 and 10.8

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
