Answer:
A
Step-by-step explanation:
Q = p(r + s)
Use the distributive property
Q = pr + ps
Q = p x r + p x s
Q = p x p + r x s
Q = p^2 + rs
Subtract rs from both sides
Q - rs = p^2
Square root both sides
sqrt Q - rs = p
Answer:
15
Step-by-step explanation:
since c is the centroid, therefore PX=XQ=1/2 x PQ
∴ PX=15
200 because 156 is closer to 200 than 100
Answer:
B
Step-by-step explanation:
1/6x+ 4/6x = -4/6
5/6x= -4/6
x=( -4/6)/ (-5/6)
x= 4/5
