If the area of the rectangle shown is given by the expression 3x2 + 72 - 6and the width is (a + 3), which of the following would represent the length? Remember: A = lw (Hint: Box method multiplication may be helpful here!)

Solve 2^x=32 and rewrite this equation in a logarithmic form

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
