Lets solve the equation first:
<span> 0.5 – |x – 12| = –0.25
</span>= 1/2 - |x - 12| = -1/4
= 2 - 4<span>|x - 12| = -1
= 4|x - 12| = 3
= |x - 12| = 0.75
positive case, x >= 12
x - 12 = 0.75
x = 12.75
negative case, x < 12
x - 12 = -0.75
x = 11.25
So those are the two solutions.
These apply:
</span>1.) The equation will have no solutions.
2.) A good first step for solving the equation is to subtract 0.5 from both sides of the equation.
<span>3.) A good first step for solving the equation is to split it into a positive case and a negative case.
</span><span>5.) The negative case of this equation is x – 12 = –0.75.</span>
Answer:
(3x-2)(x+5)
Step-by-step explanation:
First, set up an X to solve for potential factors. The two factors should add up to the middle value (13) and multiply to equal to the combined value of the first and third values (-30 (3 x -10)).
Find which two numbers can add to equal 13 and multiply to equal -30: -2 and 15.
Split the middle value into those two values like so:
3x^2 + 15x - 2x - 10
Now, factor out 3x from the first two values and -2 from the last two, like so:
3x(x + 5) - 2(x + 5)
Now, because both 3x and -2 are multiplied by the same factor, you can split the above expression into the new, factored expression:
(3x - 2)(x + 5)

without rounding it is $7.52 but you would round that to 8
Answer:
AL=l(w
2)2+h2+w(l
2)2+h2=20·(20
2)2+302+20·(20
2)2+302≈1264.91106
