Answer:
Area=80 units squared
A=base*height
A=base*height/2
Step-by-step explanation:
7*8=56/2=28
7*8=56/2=28
3*8=24
28+28+24
56+24

<u>Given</u>:
Let time be the independent variable.
Let mile marker be the dependent variable.
On one highway, Gabriela noticed that they passed mile marker 123 at 1:00. She then saw that they reached mile marker 277 at 3:00 and Mr. Morales was driving at a constant speed.
The coordinates of the points on this line are (1,123) and (3,277)
We need to determine the slope of the line.
<u>Slope of the line:</u>
The slope of the line can be determined using the formula,

Substituting the points (1,123) and (3,277) in the above formula, we get;



Therefore, the value of the slope of this line is 154.
 
        
             
        
        
        
The answer is -60=60
Simplifying
s2 + -17s + -60 = (s + -5)(s + -12)
Reorder the terms:
-60 + -17s + s2 = (s + -5)(s + -12)
Reorder the terms:
-60 + -17s + s2 = (-5 + s)(s + -12)
Reorder the terms:
-60 + -17s + s2 = (-5 + s)(-12 + s)
Multiply (-5 + s) * (-12 + s)
-60 + -17s + s2 = (-5(-12 + s) + s(-12 + s))
-60 + -17s + s2 = ((-12 * -5 + s * -5) + s(-12 + s))
-60 + -17s + s2 = ((60 + -5s) + s(-12 + s))
-60 + -17s + s2 = (60 + -5s + (-12 * s + s * s))
-60 + -17s + s2 = (60 + -5s + (-12s + s2))
Combine like terms: -5s + -12s = -17s
-60 + -17s + s2 = (60 + -17s + s2)
Add '17s' to each side of the equation.
-60 + -17s + 17s + s2 = 60 + -17s + 17s + s2
Combine like terms: -17s + 17s = 0
-60 + 0 + s2 = 60 + -17s + 17s + s2
-60 + s2 = 60 + -17s + 17s + s2
Combine like terms: -17s + 17s = 0
-60 + s2 = 60 + 0 + s2
-60 + s2 = 60 + s2
Add '-1s2' to each side of the equation.
-60 + s2 + -1s2 = 60 + s2 + -1s2
Combine like terms: s2 + -1s2 = 0
-60 + 0 = 60 + s2 + -1s2
-60 = 60 + s2 + -1s2
Combine like terms: s2 + -1s2 = 0
-60 = 60 + 0
-60 = 60
Solving
-60 = 60
