Answer:
:))
Step-by-step explanation:
Collect like terms, keeping the integer rules in mind
5. 5a + 9b - 3a + 2b + 4a
5a + 4a - 3a + 9b + 2b (REARRANGE, if you find it to help)
6a + 11b
6. 7m + 3n - 8m + 2n + 10m
7m + 10m - 8m + 3n + 2n
9m + 5n
10. 10m²n + 5mn + 9m²n - 2mn
10m²n + 9m²n + 5mn - 2mn
19m²n + 3mn
Try to do the rest on your own :)
Answer:

Step-by-step explanation:
(1/2)x
use rise over run
how many units up/down and units right/left
Down and left means negative
Answer:
f•g(x) = f(x)•g(x)
f•g(x) = (2x-1) (x²-2x+1)
= 2x³-4x²+2x-x²+2x-1
= 2x³-5x²+4x-1
Common factor is such a term which can be taken out common from each term of the expression.
If you observe the given expression, 2x can be taken out common leaving the expression which cannot be factored any further.
14x² - 12x
= 2x (7x - 6)
So 2x is the common factor. The answer to this question is option C
ANSWER
2393.9 mm³
EXPLANATION
The volume of a sphere of radius R is,

In this case, the radius of the sphere is 8.3 mm. Using π = 3.14, the volume is,

Hence, the volume of the sphere is 2393.9 cubic millimeters, rounded to the nearest tenth.
