Answer:

Step-by-step explanation:
P, A, and R are collinear.
PR = 54


To solve for the numerical length of PR, let's generate an equation to find the value of x.
According to the segment addition postulate:

(substitution)
Solve for x

Combine like terms


Add 2 to both sides


Divide both sides by 7



Plug in the value of x into the equation


Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.
Answer:1/3 to the 3rd = 1/9 units
Step-by-step explanation:
a^3 = volume of a cube part 2: 1/2 to the power of 1/2
Answer:
2370 cm²
Step-by-step explanation:
2(32·15+15·15+15·32) = 2370
A+b=(-3n+2)+(5n-7)
=(5-3n)+(2-7)
=2n-5
