Answer:
70.
Step-by-step explanation:
1) to calculate the values of the 'x':
4x+15=x²-13x+85; ⇔ x²-17x+70=0; ⇔
x₁=7; x₂=10;
2) to calculate the required k:
k=x₁*x₂; k=7*10=70.
Let be P(x, y) and Q(x, y) two <em>distinct</em> points on <em>Cartesian</em> plane, which generates a <em>line</em> segment. The slope represents the "inclination" of that <em>line</em> segment:
<h3>What is the property of slope</h3>
Slope is a relationship of the change in the <em>dependent</em> variable (y) and the change in the <em>independent</em> variable (x). In this question we should present the correct definition for slope, which is described below:

Step-by-step explanation:
=
38.64=9.2h/2
=
38.64=4.6h
=
h = 38.64/4.6
h = 8.4
thats it
2/3(6x+3)
2/3 x 3(2x+1)
2(2x+1)
4x+2
Therefore your answer is 4x+2
