Jack empties 12 Litres of water from a bucket into a tank 51cm long, 37cm wide and 28cm high that was already fill to
the depth of 7cm. How much water is needed to completely
fill the tank? Give your answer in litres and millilitres.​

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
