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

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

(23*2)-12=x     x=34

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
