9x^2 + 24 x + 16 = 0
(3x +4) (3x + 4) = 0
x=-4/3
are you sure part A doesn't have a negative somewhere?
9x^2+12x+12x+16 this works just double checking
b)
16x^2 - 25y^2 = 0
(4x-5y)(4x+5y)= 0
hope this helps
Answer:
$180
Step-by-step explanation:
To solve, we can set up a proportion and solve.
You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work
45/7.5=x/30
Cross multiply
45*30=7.5*x
1350=7.5x
To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5
1350/7.5=7.5x/7.5
180=x
So, for 30 hours of work, you would earn $180
I believe that angle 6 is 108 because I drew to the best of my ability and I see that 3 and 6 are alternate interior angles.
It’s unsolvable with out more context. What’s the rest of the problem.
