Answer:
32 + x= 90
x= 90- 32 = 58
x + y = 90
38 + y= 90
y= 90-38
y = 52
Step-by-step explanation:
Answer:

Step-by-step explanation:
There are a total of 20 marbles.
10/20 equal 50%
Step-by-step explanation:
you start with 90 then 180 then270 then 360
Answer:
2a + 8√b
Step-by-step explanation:
√9a² = 3a
√49b = 7√b
and
3a + 7√b - a + √b = 2a + 8√b
Remember that the additive inverse are two equal numbers (or expressions) but with different signs.
We have then, that according with the coment below:
(3a2 - 5ab + b2) - (-3a2 + 2b2 + 8ab)
the additive inverse is:
(3a2 - 2b2 - 8ab) Note that is the same expression that
(-3a2 + 2b2 + 8ab)
but with different signs.
Answer:
the additive inverse of the polynomial being subtracted is
(3a2 - 2b2 - 8ab)
