X^2 + 6x = -2 is a quadratic equation that can be solved by completing the square.

x^2 + 6x + (6/2)^2 - (6/2)^2 = -2

Rewriting this, (x+3)^2 = -2 + (6/2)^2 = -2 + 9 = 7

tAKING THE sqrt f both sides, we get x+3 = plus or minus 5.

Finally, x = -3 plus or minus 5, which boils down to x=2 and x= -8.

Sum of money is placed at simple interest for 3 years at 10% per annum and then the amount is invested for 2 years at the same r

JulsSmile [24]

Answer:

sum was 300000

Step-by-step explanation:

let sum of money is placed is x rs

Term T = 3 years, rate R = 10%

Then simple interest for for 3 years is

$SI= \frac{PTR}{100}\\ SI=\frac{x\times 3\times 10}{100} \\SI = 0.3x$

Sum of x will become x+0.3x = 1.3x after 3 years. now this 1.3x is kept for compound interest for two years. ie

$A =P[1+R]^t\\471900=1.3x[1+\frac{10}{100} ]^2\\x=\frac{471900}{1.573} \\x=300000$

Sum was 300000

Goshia [24]

Answer:

If I am assuming sqrt(200), the answer is C

Step-by-step explanation:

$14^{2} = 196\\15^{2} = 225$

Because 200 is between both of these numbers, c is the only viable option

Answer:

Choice C

Step-by-step explanation:

$-3.55g \le -28.4$

Divide both sides by -3.55; remember that by dividing both sides of an inequality by a negative sign, you need to change the direction of the inequality sign.

$\dfrac{-3.55g}{-3.55} \ge \dfrac{-28.4}{-3.55}$
