10. Both segments are considered congruent, so turn both expressions into an equation:

Plug this back into the equation to get
on both sides.
9. All edges in a square obtain congruent right angles and edges, so set
equivalent to the given expression:

8. Both angles are considered supplementary, so turn both expressions into an equation and set it to one hundred eighty degrees:

Answer:
d. 6
Step-by-step explanation:
The product of lengths to the near and far intersection points is the same for both secants:
PB×PA = PD×PC
We can use this relation to solve for x, then use the value of x to find PD.
7×12 = (3x)(7x)
4 = x² . . . . . . . . . divide by 21
2 = x . . . . . . . . . . take the square root
__
PD = 3x = 3·2
PD = 6
Answer:steepness
Step-by-step explanation:
Answer:


Step-by-step explanation:
Given

per mile
Solving (a): Linear Equation
The total charges (c(x)) is: the base charge + the rate * number of miles (x).
So, we have:


Solving (b): Cost of rent, if miles = 160
This implies that x = 160
So, we have:
