It depends on what level of classes you take, but algebra classes in college do tend to be harder than algebra classes in high school or middle school.
Answer:
(x-5) (x-2)
Step-by-step explanation:
x^2 (-2x-5x) +10
basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
you can work it out or put in random numbers until the two sides are equal
It is going to 21 because when you is divid 386÷18=21and you don't have 21 up there either I did it wrong or you do not have up there bc you missed up
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add
50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750
750 grams of water
