Solve by taking the square root of both sides (3x+3)2 =25 Please enter any square root values using "sqrt" or the decimal answer rounded to the nearest hundredth (i. e. = sqrt(2) or 1.41).

x= 2/3 or -8/3

Step-by-step explanation:

(3x+3)^2 = 9x^2 +18x+9

therefore

9x^2 +18x+9 = 25

subtract 25 on both sides

9x^2 +18x-16 = 0

9(x^2+2x) - 16

or  substitute into the quadratic formula and you get

x= 2/3 or -8/3

-14 is the answer

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
