2x^2-9x+9? I have to simplify

Mathematics
1 answer:
denis23 [38]2 years ago
6 0

Step-by-step explanation:

Assuming you meant to factor (comment and ill update if you didnt)

we can use the AC method

multiple the A term(2) by the c term(9)

and then factor by grouping 2x^2+9x+9\\2x^2+9x+18 (We\ use\ 18\ to\ get\ more\ factors,\ then\ we\ set\ it\ back\ to\ 9)\\2x^2+6x+3x+9\\\\2x(x+3)3(x+3)(2x+3)(x+3)

A ship has 1400 people on board. There are 200 more adults than children. How many children are on the ship?
kenny6666 [7]

So,

1400 people in total. Though, subtract 200 for the amount of extra adults. This makes 1200. Divide that by two. You get 600

You need to add 200 to the 600 to get the amount of adults. The amount of adults on board is 800.

The amount of children on board is 600.

600 plus 800 equals 1400, it makes sense. :P

Can someone pls help with these geometry questions, it’s urgent.
Phantasy [73]

Answer:

6. x + x + 14 = 90

   2x + 14 = 90

   2x = 76

   x = 38

angle b = 38 + 14 = 52°

7. angles on a straight line add up to 180°

   x + x - 32 = 180

   2x = 212

    x = 106°

angle d = 106 - 32 = 74°

8. vertically opposite angles are equal

   7x - 80 = 3x

    -80 = -4x

     20 = x

angle 1 = 7(20) - 80 = 60°

angle 2 = 3(20) = 60°

PLEASE HELP FAST!<br><br><br> what is the length of segment AB? <br> 10<br> 12<br> 13<br> 15
ss7ja [257]

Answer:

13

Step-by-step explanation:

This triangle appears to be 5 units wide and 12 units tall.

Using the pythagorean theorem, a^2 + b^2 = c^2, we get 25 + 144 = 169 or 13^2.

Therefore the answer is 13.
