You find two numbers that add up to the  5  and multiply to the  -6 .

It looks like  6  and  -1  can do the job ...

              adding:           6 + (-1)  =  5
              multiplying:     6 x (-1)  =  -6 .

See ? OK.  So now, the factors of the expression are

     ==>  (x plus one of the numbers)
and
     ==>  (x plus the other number).

           (x + 6) (x - 1)  =  x² + 5x - 6

I'm assuming the "squared" is x^2+5x-6 in which case the answer is (x+6)(x-1)

Serga [27]

Answer:

a) 11%

b) 56%

Step-by-step explanation:

a) A= πr^2    6^2π= 36π    A= 18^2π = 324π

36π/324π = .111111111111111111111111 or 11%

remember to cancel out the pi symbols when you are showing your work

(put a line across the pi symbols when dividing)

b)   A= πr^2         18^2 π = 324π

     A= πr^2          12^2π = 144π  

              324 – 144  = 180

180π/324π = .5555555555555555555555556 or 56%

remember to cancel out the pi symbols when you are showing your work

What is 3/4 + 2/3 ???
erica [24]
To add fractions, first convert them to have equal denominators.

3/4= 9/12 (multiply both sides by 3)
2/3= 8/12 (multiply both sides by 4)

From here, add the numerators while keeping the denominator.
9/12+ 8/12= 17/12

Final answer: 17/12 or 1 5/12
