Answer:
x = -2 or x = 1/2
Step-by-step explanation:
First get the eq in standard form, which means:
x² should not have that 2 in front of it
move the other 2 to the left
so first let's divide by 2:
x² + 3/2 x = 1
now move the 1 to the left
x² + 3/2 x - 1 = 0
now look for two numbers that, when multiplied, give -1, and when added, give 3/2. This is a bit of trial-and-error if you want to solve in this way.
The numbers are 2 and -1/2, since 2*-1/2 = -1, and 2 - 1/2 = 3/2
The factorization thus is:
x² + 3/2 x - 1 = (x+2)(x-1/2) = 0
Either factor (x+2) or (x-1/2) can be zero to solve the solution, hence x = -2 or x = 1/2
Answer:
The number of goody bags inside the box=40
Step-by-step explanation:
Given the box weighs 200g
given the weight each goody bag be 150g.
Let the number of goody bag be x
Also given that the weight of the bag Long with the goody bags is 6.2Kg.
We know that 1Kg =1000 g.
So total weight=
=6200g
Total weight=weight of the bag + the number of goody bags * the weight of each goody bag.
Now
6200=200+
=40
Therefore there are 40 goody bags
