Solve 2x^2 +16x+50=0

musickatia [10]

$2x^2 +16x+50=0\ \ \ \ \ |:2\\\\x^2+8x+25=0\\\\x^2+2\cdot x\cdot4+25=0\ \ \ \ |+4^2\\\\\underbrace{x^2+2\cdot x\cdot4+4^2}_{(a+b)^2=a^2+2ab+b^2}+25=4^2\ \ \ \ \ |-25\\\\(x+4)^2=16-25\\\\(x+4)^2=-9 < 0-NO\ REAL\ SOLUTION$

$COMPLEX\ SOLUTIONS\\\\(x+4)^2=-9\to x+4=\pm\sqrt{-9}\\\\x+4=-3i\ \vee\ x+4=3i\ \ \ \ |-4\\\\x=-4-3i\ \vee\ x=-4+3i$

Help me with this parallelogram please :)

antoniya [11.8K]

Parallel sides of parallelogram are equal in length

$\\ \sf\longmapsto AD=BC$

$\\ \sf\longmapsto 6x+14=9x-4$

$\\ \sf\longmapsto 9x-6x=14+4$

$\\ \sf\longmapsto 3x=18$

$\\ \sf\longmapsto x=6$

AD=6x+14=6(6)+14=36+14=50

Brittany opened a savings account with an annual interest rate of 10% and an initial deposit of $7000. If her interest is compou

GenaCL600 [577]

Initial Deposit = $7000

It means P= $7000

rate of interest = 10%

So , r = 0.10

compounded quarterly , so n = 4

and we have to find the amount after 5 years , So t = 5

Now the formula we use here is

$A= P(1+\frac{r}{n} )^{nt}$

$A= 7000(1+\frac{0.10}{4} )^{(4)(5)}$

$A= 7000(1.025 )^{(20)}$

$A= 7000(1.63861644029)$

$A= 11470.315$

So amount after 5 years = $11470.315
