6. 3x - 3
7. -2b + 12
8. 2y-12
You can calculate it using the law of cosines: c^2=a^2+b^2-2*a*b*cos(C)
your triangle is
CD=15=a
CE=?=b
DE=CE+3=b+3=c
and C=90°
-> insert those values, with c substituted with b+3 to remove c
c^2=a^2+b^2-2*a*b*cos(C)
(b+3)^2=15^2+b^2-2*15*b*cos(90)
cos(90)=0->
(b+3)^2=15^2+b^2
b^2+2*3*b+3^2=225+b^2
6b+9=225
6b=216
b=36=CE
DE=CE+3=36+3=39
Answer: $4.70
Step-by-step explanation:
if you divide the cost of the 8 cans by 8 we know that each can costs approximately $0.47. so, if we multiply 10 times 0.47 we get 4.7 or $4.70
