Answer:
Hi,
Step-by-step explanation:
1) PC=PD since PC*PA=PD*PB
2)25 since PO²=PA²+r² PO=14.5, PB=14.5+10.5=25
3)
6²=3*x==> x=12
First you are going to distribute and you are going to get 8c-72=12c-72-4c.
Next you are going to combine like terms you get 8c-72=8c-72.
Then move the Varible to one side and solve for the Varible you should get c=0
Hello,
6x²+2x-20=0
==>6x²+12x-10x-20=0
==>6x(x+2)-10(x+2)=0
==>(x+2)(6x-10)=0
==>x=-2 or x=5/3
Answer: a. Every ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation: The proportionality between two variables x and y is established using the proportionality relation.
x = ky where k is a constant and k = x / y. Hence every ratio of both numbers for a rated pair are equivalent once x and y ≠ 0
Answer:
50 feet
Step-by-step explanation:
According to the Pythagorean theorem a^2+b^2=c^2 and if you put it into this equation it is 30^2 + 40^2 =50^2 which does work out
