Help!! Its A Math Problem ! I am not sure how to solve it!! or show my work

Step-by-step explanation:

#1.

2x² + 24x + 10 = 0

2(x² + 12x + 5) = 0

2[ x² + 2(6)x + 6² - 6² + 5 ] = 0

2[(x + 6)² - 31] = 0

2( x + 6 - √31 )( x + 6 + √31 ) = 0

= - 6 + √31

= - 6 - √31

#2.

f(x) = 3x² - 36x - 12

f(x) = 3( x² - 12x - 4 )

f(x) = 3 [ x² - 2(6)x + 6² - 6² - 4 ]

f(x) = 3 [( x - 6 )² - 40 ]

f(x) = 3( x - 6 )² - 120

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

mark brainliest!

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
