Answer:
Third and sixt option
Step-by-step explanation:
Applying the distributive property:
(b-2c)(-3b+c)=b(-3b)+b(c)-2c(-3b)-2c(c)
(b-2c)(-3b+c)=-3b^2+bc+6bc-2c^2
Adding like terms:
(b-2c)(-3b+c)=-3b^2+7bc-2c^2
The simplified product has 3 terms (first and second option are not true)
The simplified product has a degree of 2 (third option is true)
The simplified product, in standard form, has exactly 2 negative terms: -3b^2 and -2c^2 (sixth option is true)
Since the object is a cube, times 42 three times by itself. You have to do this because it is length x width x height. 42 x 42 x 42. The answer you're looking for is 74,088 cubic inches because it is three-dimensional.
Call the price of the bike before mark up 'x', then we have:
x + 0.25x = 210
1.25x = 210
x = 168
Therefore, the bike cost $168 before 25% price increase.
It is 30-88 degrees I think
