To figure out what the numerical value of the variable is
c=52, a=2b+8
<span>
Pythagorean Theorem = a^2+b^2=c^2</span>
<span>
(2b+8)^2+b^2=52^2</span>
<span>
<span>
4b^2+32b+64+b^2=2704</span></span>
<span><span>
5b^2+32b-2640=0 </span></span>
<span>
b=20 </span>
a= 2(20)+8 =
48
<span>48+20+52
= 120</span>
Check your book on Cavalieri's Principle.
Cavalieri's Principle:
two solids that have the same altitude and identical cross-sections all the way up, though slanted or not, have the same volume.
Y=12x hope you have a good day
Answer:
Step-by-step explanation:
We can add the same quantity to both sides of the equations, and still have an equivalent equation. Let's add to both sides, then sum like terms
(this is the rule that allows us to move items from one side do the other of the equal sign by changing its sign)
At this point we have a solution, let's replace it to verify
