8x^2+2x-3
factor
()()
find what 2 numbers multiply to get -3 and add to get 2
the answer is -1 and 3
then what 2 numbers multiply to get 8
(2x-1)(4x+3) is the factored form
We know, 1 yard=3 feet.
1 feet =12 inches.
Therefore, 1 yard in inches is,
Hence, 3 yards in inches is.,
Therefore, 3 yards is greater than 107 inches.
134,217,728/16,777,216
Even more simplified dividing them would equal 8
Answer:
0.85 > 0.819
Part B: Jason is not correct.
Step-by-step explanation:
Length as per Marco = 0.85 meters
Length as per Jason = 0.819 meters
It can be clearly seen that both the quantities are lesser than 1.
and length of desk as per Marco is greater than the length as per Jason.
So, the answer is:
0.85 > 0.819.
Part B:
Jason says his measurement is greater than Marco's measurement because 819 is greater than 85.
Here no doubt that 819 > 85 is true.
But, here we are dealing in decimals and the quantities are:
0.819 and 0.85 which can also be written as 0.850.
And therefore, 0.850 > 0.819 i.e. <em>Jason is incorrect</em>.
X^2 + x(x - 5) - x + 7
x^2 + x^2 - 5x - x + 7
2x^2 - 6x + 7
