Given:
1 of 3 pasta meals
1 of 7 chicken meals
1 of 3 fish meals
Simply multiply the total number of choices:
3 x 7 x 3 = 63
Ping can choose a dinner meal in 63 ways.
Step-by-step explanation:
the answer is -86 mark as brainliest or rate this if u found this helpful :)
Width = w
Length = 3w - 6
Area = 360
Equation Area = wl
w (3w-6) = 360
3w^2- 6w = 360
3w^2 - 6w - 360 = 0
3 (w^2 - 2w - 120)=0
3(w + 10)(w - 12) = 0
w = -10 & 12
l = 3w-6 = 3 (-10)-6= -30 - 6= -36
l = 3w-6 = 3(12) - 6 = 36-6 = 30
Answer: -10 and 12. Yet, since this is a measurement, it must be positive so 12 ft

x^2+2x+8=0
x^2+2x+1+7=0
(x+1)^2= -7
(x+1)^2= i^2.7
x+1= i.square root of 7
x=-1+ i.square root of 7
