Square both sides to get the binomial out of the square root:
(√(2x + 8))² = (2)²
2x + 8 = 4
2x = 4 - 8
2x = - 4
Divide both sides by 2 to isolate the variable X:
x = - 4 / 2
x = - 2
Your answer is option C.
Divide by 3 then subtract however many you have to
Answer:
a = 324
Step-by-step explanation:
9=1/27 a -3
value of a = ?
9=(1/27) a -3
9 + 3 = (1/27) a
12 = (1/27) a
12 x 27 = a
a = 324
Each year, your $3,425 which earn 3% simple interest earns $102.75. Multiplying this value by 15 gives $1541.25. Then, adding the latest value we have with the initial invest will finally give us $4966.25. Thus, after 15 years Naomi will have $4966.25.
