Answer:
Plant will take 29 days to reach 122 cm in height .
Option (c) is correct .
Step-by-step explanation:
Let us assume that x be the number of days plant will take to reach 122 cm in height .
As given
A vine 6 cm tall is planted in a garden. it grows 4 centimeters a day.
Equation becomes
Total height = Height of the plant + Height grow everyday × Number of days .
122 = 6 + 4 × x
122 = 6 + 4x
122 - 6 = 4x
116 = 4x
x = 29 days
Therefore plant will take 29 days to reach 122 cm in height .
Option (c) is correct .

Answer:
CE = 17
Step-by-step explanation:
∵ m∠D = 90
∵ DK ⊥ CE
∴ m∠KDE = m∠KCD⇒Complement angles to angle CDK
In the two Δ KDE and KCD:
∵ m∠KDE = m∠KCD
∵ m∠DKE = m∠CKD
∵ DK is a common side
∴ Δ KDE is similar to ΔKCD
∴
∵ DE : CD = 5 : 3
∴
∴ KD = 5/3 KC
∵ KE = KC + 8
∵
∴
∴
∴
∴
∴ KC = (8 × 9) ÷ 16 = 4.5
∴ KE = 8 + 4.5 = 12.5
∴ CE = 12.5 + 4.5 = 17
