If you mean (√3 + √2)^2 then this is 3 + 2√3√2 + 2 → 5 + 2√6

.

it's not a bug it's the correct answer

You have to work out the 2 solutions for x, then you can factor it in the form of: y = a(x-x1) + (x-x2) 

what is the answer to x^2=0.49

x^2=0.49 take the sqrt of both sides.

x = sqrt(.49)

x=0.7

Solve for x over the real numbers:
abs(3-2 x) = 7

Split the equation into two possible cases:
3-2 x = 7 or 3-2 x = -7

Subtract 3 from both sides:
-2 x = 4 or 3-2 x = -7

Divide both sides by -2:
x = -2 or 3-2 x = -7

Subtract 3 from both sides:
x = -2 or -2 x = -10

Divide both sides by -2:
Answer: |x = -2                or                      x = 5

W=V x Amps.

550 / 1,000 =.550 Amps.

W = .550 x 230 =~127 Watts - power consumed by light bulb.

z=-36+12

z=-24

None of them!!.

Divide inches by 12 to get feet.

Volume of Sphere=4/3. r^3. Pi

Thank you so much

A spherical ballon is being inflated in such a way that its radius is increasing at the constant rate of 3cm/min.\(\Rightarrow \frac{dr}{dt}=3cm/min\)

The relation between the volume and radius of the spherical ballon is \(v(r)=4*{r}^{3}/3\)

The dervative of volume v  respect to variable v is \(\frac{dv}{dr}=4{r}^{2}\)

At time 5 minutes \(\frac{dv}{dr}=4*5^2=100\)cm^2

Applying chain rule,\(\frac{dv}{dt}=\frac{dv}{dr}*\frac{dr}{dt}\)

\(\frac{dv}{dt}=100*cm^2*3cm/min=300cm^3/min\)

This is a kind of problem relative rate of change,application of differvative.

Multiply 38% by 450. 38% in decimal form is .38 so you get the answer from .38*450

1 1/4= (1*4+1)/4 = 5/4

plug it in, 

-2 x -2= 4

then do the other side, -2 x -3 = 6

now combine the two, so your equation should look like this:

4+6

The answer is 10

.1111111111111111...........etc =1/9

Speed =Distance travelled/ Time

Time =Distance travelled/ Speed

T = D / 30 The time it took her to drive to Fixit.

T = D / 20 The time it took her to ride the bus home.

D / 30 + D / 20 = 1 hour, solve for D,

D = 12 Miles from her house to Fixit.

Most calculators simplify answers themselves 

i really need help 

-1, because when a negative number is multiplied by a negative it becomese a positive.  Thus, choose -1 because 1 doesn't do anything.

It all depends on the INTEREST RATE that you can get for your money:

@ 5% you have to deposit $166,945 when you are 15 years old.

@7% you have to deposit $$71,420 when you are 15 years old.

@10% you have to deposit $20,579 when are are 15 years old.

for help math

At age 10​, a person deposits ​$365 in a savings account paying 2​% interest compounded semiannually. How much money will be in the account 65 years​ later, when he is 75 years​ old? Would his savings have doubled in that​ time?

At 75 the person's $365 should have have grown to $1,330.67 @ 2% comp. semi-annually.
