Answer:
Assuming the 2 at the ends are the exponents,
the answer is -x^2-5x+6 (x^2+5x-6)
from here, it cannot be simplified more
Explanation --
Just add everything by putting the terms in parentheses and adding them.
Keep simplifying by putting the like terms together and adding/subtracting them.
At the end, you come up with -x^2-5x+6, so multiply -1 on the whole thing (by putting parentheses on its sides. This makes x positive. But they are the same thing, but this step is just for simplifying the end product a little more.
Hope this helps!! Have a nice day!
Answer:
x=-11
Step-by-step explanation:
-3(x+2)=16-x
start with parenthesizes
-3*x=-3x
-3*2=-6
so you get
-3x-6=16-x
add the 6 to both sides
-3x=22-x
add x
-2x=22
divide by -2
x=-11

Answer:
Part a) 
Part b) 
Step-by-step explanation:
we know that
A reciprocal of a rational number 
is obtained by changing the numerator and denominator, so the numerator becomes the denominator and the denominator becomes the numerator obtaining 
Part a) we have
200
we know that
the given number can be expressed as 
so
changing the numerator and denominator
The reciprocal is equal to
Part b) we have
450
we know that
the given number can be expressed as 
so
changing the numerator and denominator
The reciprocal is equal to
The scale used to make the model was 125 meters = 1 foot. 525 divided by 4.2 equals 125 meters.
The mode is 84 sheets of plywood tall.
4.2 feet = 50.4 meters
50.4 meters divided by 0.6 equals 84 sheets.
