Answer:
The width of the area model is equal to

Step-by-step explanation:
<u><em>The complete question is</em></u>
Todor was trying to factor 10x^2-5x+15 he found the greatest common factor of these terms was 5 what is the width
we know that
The area of a rectangular model is given by the formula
----> equation A
where
L is the length
W is the width
we have

Factor the expression
substitute the value of the Area in the equation A

In this problem
The greatest common factor of these terms is the length (L=5 units)
so
we can say that the width is equal to (2x^2-x+3)
therefore
The width of the area model is equal to

Answer:
- 7 / 4
Step-by-step explanation:
( x1, y1 ) = ( 1, 10 )
Here,
x1 = 1
y1 = 10
( x2, y2 ) = ( 5, 3 )
Here,
x2 = 5
y2 = 3
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 3 - 10 ) / ( 5 - 1 )
Slope = - 7 / 4
Proper fraction = - 7 / 4
Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
