In making a lawn in the garden, the cost of fencing is $20 per metre and the cost of flower -planting is $50 per metre square. Let x be the length of a side of the lawn in metres.
(a) If $ F is the cost of constructing the fence, find a formula connecting F and r.
(b) If $ Pis the cost of flower-planting, find a formula connecting P and x.
(C)
If $ T is the total cost of making the lawn, find a formula connecting T and x.​

the image of (6, 9) under a dilation is (4, 6). the scale factor is

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

hope this
