9: I think it is 48
10: 138
Simple math. 350 - 90 = 260. So Hector needs to drive 260 km more to reach his cousin
Answer:
(x-4) (x-3) (x+3)
Step-by-step explanation:
x^3 - 4x^2 - 9x + 36
Make 2 groups
x^3 - 4x^2 - 9x + 36
We can factor out x^2 from the first group and -9 from the second group
x^2 (x-4) - 9(x-4)
Now factor out (x-4)
(x-4) (x^2 -9)
This may be an answer choice but we can still factor
(x^2 -9) is the difference of squares
(x^2-9) = (x-3) (x+3)
Replacing this
(x-4) (x-3) (x+3)
Quotient of x and 9=
And 7 less than from it means=
(Answer)
Sum means add
x and y are the numbers
sum i 44
x+y=44
smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y
substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32
the numbers are 12 and 32
