Answer:
 x2-5x-8=0  
Step-by-step explanation:
Two solutions were found :
 x =(5-√57)/2=-1.275
 x =(5+√57)/2= 6.275
Reformatting the input :
Changes made to your input should not affect the solution:
 (1): "x2"   was replaced by   "x^2".  
Step by step solution :
Step  1  :
Trying to factor by splitting the middle term
 1.1     Factoring  x2-5x-8  
The first term is,  x2  its coefficient is  1 .
The middle term is,  -5x  its coefficient is  -5 .
The last term, "the constant", is  -8  
Step-1 : Multiply the coefficient of the first term by the constant   1 • -8 = -8  
Step-2 : Find two factors of  -8  whose sum equals the coefficient of the middle term, which is   -5 .
     -8 + 1 = -7  
     -4+  2 = -2  
     -2+  4	= 2  
     -1	+   8	= 7

Answer:
I'm going to help youuuuu. 
Step-by-step explanation:
{1} 
Your answer is A) because the rise/run is -2/4x, which simplifies to -1/2x, which is <em>option A)</em>.
{2} 
Dario's salary is <em>B) $12 per hour</em>. This is because, in 5 hours, Dario makes 60 dollars. If you find the unit rate of $60 in 5 hours, the answer is $12 per hour. 
{3}
A) Between <em>x = -6</em> and <em>x = -2</em>
I hope this helps! I am sorry if any of these are incorrect!

work:
75 is equal to 2x+15
75-15 = 60
60/2 = 30
x=30
        
             
        
        
        
Answer:

Step-by-step explanation:
<u>Surface Areas
</u>
Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.
Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is

The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus

The back left area is another rectangle of 4.5 mm by 9 mm

Finally, the back right area is a rectangle of 6 mm by 9 mm

Thus, the total surface area of the prism is
