Complete the square
isolate x terms
y=(x^2-14x)+53
take 1/2 of -14 and square it ((-7)^2=49
add plus and minus of that inside the parntehasees
y=(x^2-14x+49-49)+53
factor perfect suqrae
y=((x-7)^2-49)+53
get rid of parnthasees
y=(x-7)^2-49+53
y=(x-7)^2+4
C isi answer
Answer:
1/4 cups of juice
Step-by-step explanation:
1 cup of juice --- 4 cups of water
x cups of juice --- 1 cup of water
1/x = 4/1
1/x = 4
x = 1/4
∆LNR~∆MNP=>LN/NM=NR/NP=>12/8=X+6/6=>X+6=12*6/8=>X+6=9=>X=9-6=>X=3. :D
Tan(pi/4)=1=sin(pi/4)/cos(pi/4)=(2^1/2)/2)/(2^1/2)/2)
