For those that can't see the pic clearly, John has 315 pieces of square tiles, each of side 30cm long. i) find the minimum number of such tiles he should buy more of so that he can lay a large square with all the tiles

ii)Hence find the area of the large square

*btw the lvl for this is sec 1 and the topic is prime factors

ou would have 12 of each

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

∠cbe and ∠deb are same-side interior angles.

i took the test

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
