D/dx ( cos (4x)) = - sin (4x) · d/dx ( 4x) = - 4 sin (4x)
-2 x (3y - 8) would be the answer
Surface area= [15*3*2]+[20*3*2]+[10*3*2]+[14*3*2]+[15*3*2]+[14*2.5*2]
surface area=90+120+60+84+90+70=514 in²
the answer is 514 in²
8y+10
if the fabric = 30 and yards = y then you would put 8(30) + 10 and you would multiply 8 and 30 and get 240.
Asnwer
8y+10
8(30) +10
240 +10
250
