Express the area of the entire rectangle . Your answer should be a polynomial in standard form. x+3 x+9

Area of the rectangle = ( x²+12x+27)unit²

Step-by-step explanation: Length = x+3  Breadth = x+9

∴ Area of Rectangle = L×B

(x+3)(x+9) = x²+9x+3x+27 = (x²+12x+27) unit²

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
