It would be (x-6)(x-9)

We know that X^2 factors out to x times x

54 could factor to 27*2, 54*1, 6*9, 3*18. You would need to find two numbers that would multiple to equal 54 and add up to equal -15. These two numbers would be -6 and -9. So the answer is (x-6) (x-9)

Answer:

x= 6 x= 9, or (x-6)(x-9)

Step-by-step explanation:

Find factors of 54.

1x54

2x27....so on

6x9

Find out which factors add or subtract to 15, knowing that 54 is positive, the two factors have to be either both negative or positive.

Then look at the middle number, -15. With it being negative, both factors will be negative because it is negative.

So, -6+-9=-15.

Next x^2 is actually x*x, so when you factor, one single x will go with one factor, and then you will pair the other two.

Alex is practicing his dives at a pool. He dives from the diving board that is 15 feet above the surface of water. His dive take
Mashcka [7]

Answer:

Alex is wrong in calculating his dive distance.

Actual distance of his Dive is 30 feet.

Step-by-step explanation:

Given:

Distance from where he dive from = 15 feet

Distance he reached after dive = 15 feet

Also Given:

Alex says that the two distances are opposites,

Also Total distance of dive according to Alex = 15 +-15 =0 feet

Solution:

Now we know that;

The diving board is 15 feet above the water level, and then he reached 15 deep in the water, but here it is important to know that even he is above the surface of the water he is diving in the water and then he reached 15 deep in the water.

So the two distances are in the same direction.

From above scenario we can say that

Total Distance of dive will be = 15 +15 =30 feet.

Hence We can say that Alex is wrong in calculating his dive distance. Actual Dive distance is 30 feet.

-8=6+x and 10=2+y

x=-14 and y=8

Therefore the required value of R{-14,8}
