Hiii! can someone please help me with my maths question

beks73 [17]

Step-by-step explanation:

a^2 + b^2 = c^2

(x+2)^2 + 4x^2 = (3x+4)^2

(x+2)(x+2)+ 4x^2= (3x+4)(3x+4)

x^2 + 2x + 2x + 4 + 4x^2 = 9x^2 + 12x + 12 x + 16

5x^2 + 4x + 4 = 9x^2 + 24x + 16

-4x^2 - 20x - 12 = 0

now we can use the quadratic formula

(-b±√(b²-4ac))/(2a)

I can't type all this so

.....

x = -0.697224362 or -4.302775638

AB can't be negative so it's the first one

so it's equals to 1.302775638

La cantidad será de 9897.47€.

Step-by-step explanation:

Future value with annuity:

The future value formula, for an annuity, is:

$FV = \frac{P((1+r)^{n} - 1)}{r}$

An annuity means that a number of payments happen during the period(an year, for example.

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

1000 € each year, so $P = 1000$

Interest rate of 6%, so $r = 0.06$

One application per year for 8 years, so $n = 8$

Total amount:

$FV = \frac{1000((1+0.06)^{8} - 1)}{0.06} = 9897.47$

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.
