The next number in this pattern should be A)28
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
U have a solid line...means there is an equal sign in the problem...so that eliminates 2 of them right away...so A and D are incorrect
it is shaded below the line....this means it is less then...that eliminates option C leaving u with only one answer choice
so ur answer is : B. y is less then or equal to x
(a^3 - 2a + 5) - (4a^3 - 5a^2 + a - 2)
=a^3 - 2a + 5 - 4a^3 + 5a^2 - a + 2
= -3a^3 + 5a^2 - 3a + 7
