Answer:
1. (x+8)(x-4)
2. 3x-20
Step-by-step explanation:
1. x² + 4x – 32
x² + 8x - 4x - 32
x (x+8) - 4 (x+8)
one of the x+8's is cancelled out then you have (x+8)(x-4)
2. x2 + x - 20
2x+x-20
3x-20
Answer:
Step-by-step explanation:
Since we know that Ivan finished all his science problems (3) we know that there are only math problems remaining
substract the science problems from the total 43-3=40
And now we can determine the amount of math problems
4/5 = 40/x where x is the total amount of math problems Ivan was assigned
cross multiply
4x = 5*40
4x=200
isolate the variable
4x/4 = 200/4
x=50
So Ivan was assigned a total of 50 math problems
(Note*) since there are 40 math problems finished 40/50 is equal to 4/5. Just a tip if you don't want to do the whole calculation
Hope this helps!
