Answer:

x = - 4

Step-by-step explanation:

= − ± 2 − 4 / 2

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

x2+8x+16=0

= 1

= 8

= 1 6

x= − 8 ± 8 ^2 − 4× 1 × 1 6 / 2× 1

= − 8 ± 64 − 4× 1 ×1 6 / 2× 1

= − 8± 6 4 − 6 4 / 2× 1

x = -8 / 2× 1

x = -8 / 2

x = -4

Hope this answer helps you :)

Have a great day

A sample of 100 wood and 100 graphite tennis rackets are taken from the warehouse. if 13 wood and 10 graphite are defective and

Nimfa-mama [501]

Let's split the problem in non-intersecting subsets: we have $87$ good wood racquets, $13$ defective wood rackets, $90$ good graphite racquets, $10$ defective graphite rackets.

The probability that the racket is wood or defective covers the following subsets: good wood, defective wood and defective graphite, which have, respectively, $87$ , $13$ and $10$ elements.

Since the total is $200$ elements, the probability is
