<h3>
Answer: PC = 5</h3>
================================================
Work Shown:
AB+BC+CD = AD .... segment addition postulate
BC+BC+CD = AD ... replace AB with BC (since AB = BC)
BC+BC+BC = AD ... replace CD with BC (since BC = BC)
3*BC = AD .... combine like terms
3*BC = 12 .... replace AD with 12
BC = 12/3 .... divide both sides by 3
BC = 4
For right triangle PBC, the legs are BP = 3 and BC = 4. We can use the Pythagorean Theorem to find that the hypotenuse is PC = 5
The steps are shown below
(BP)^2+(BC)^2 = (PC)^2
3^2+4^2 = (PC)^2
9+16 = (PC)^2
25 = (PC)^2
(PC)^2 = 25
PC = sqrt(25)
PC = 5
The other parts of the diagram seem to be thrown in as a distraction.
F(x)= (x-2) (x2-9) = (x-2)(x-3)(x+3)
Answer:
4
Step-by-step explanation:
2-(-2)=2+2=4
It's 10.
7*4=28.
280/28 = 10.
Hope this helps.
$1000 - ($20 + $20) = $60
$60 / $10 = 6 paper weights
