12ft x 15ft = 180ft divided $150 = 1.2(this is how much the fts cost)
16ft x 20ft = 320ft divided by 1.2 = $266.66
5+х-2+8=0
х+5-2+8=0
х+11=0
х=0-11
х=-11
The answer is: c you should know that it's easy
The partial products are: 42 x 28 = (40 + 2) x (20 + 8) = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8
= 800 + 320 + 40 + 16 Hope this helped.
Replace the x by x+3
so it would be
4log(x+3)
