Answer:
x=150
Step-by-step explanation:
Since f is flat, that means that the total degrees will equal 180°.
Therefore, because of the 60° and (x-30)° angles being supplementary angles,
will equal 180.

1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7
2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left
to divide on the right, multiply fraction by its reciprocal/inverse
x= 32 * 9/8
multiply numerators (top)
x= (32*9)/8
x= 288/8
x= 36
ANSWER: 1) x= -6.7; 2) x= 36
Hope this helps! :)

Answer:
first option
Step-by-step explanation:
Given
(3x² + 2x - 3)(x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x²(x - 1) + 2x(x - 1) - 3(x - 1) ← distribute parenthesis
= 3x³ - 3x² + 2x² - 2x - 3x + 3 ← collect like terms
= 3x³ - x² - 5x + 3
