Answer:

12cm long x 24cm = Area 268cm

24,53cm height was cut off this we are not given the length, so this stays 24.53cm.

The 12cm length has been altered.

Which choice is equivalent to the quotient below when. The problem is in the photo below.i am scared please
NeTakaya

Hello from MrBillDoesMath!

Answer:

Choice C, sqrt(3-x)

Discussion:

Have no fear, MBill is here!

The quotient is

sqrt (9-x^2)  / sqrt( 3+x)  =         => as sqrt(a)/sqrt(b) = sqrt(a/b), b <> 0

sqrt (   (9-x^2)/( 3+x) )  =             => as 9 - x^2 = (3-x) * (3+x)

sqrt (  (3-x)(3+x) /(3+x) ) =           => cancel (3+x) from num. and denom.

sqrt( 3-x)

This is Choice C

Note the domain restriction -3 < x < = 3 guarantees that division by zero can't happen.

Thank you,

MrB

Multiply both sides by 4 to isolate the x term.

x = 5 × 4

x = 20

What is being done to the variable in the equation = -40?
larisa86 [58]

Answer:

It's being divided by 5.

Step-by-step explanation:

In this question, the variable being used in the equation is being divided by 5. This is represented by the / symbol in the equation which is the symbol for division. If we multiply both sides by 5 we can isolate the variable M and get its value like so...

M/5 = -40   ... multiply both sides by 5

M = -200

Therefore in this scenario, the value of M would be -200

3x^2-9x+0<br> Factor the trinomial
sineoko [7]

Answer:

3x (x-3)

Step-by-step explanation

3x^2 - 9x + 0

The equation.

3x^2 - 3^2 × x

What I did here is that I factored out 9x to 3^2 times x.

3x (3x^2 all over 3x - 3^2 × x/ all over 3x)

So that way I can divide the number in the parentheses by 3x to take 3x out of the parentheses to factor out.

3x (x^2-1 - (3^2-1) )

You simplify to get the final answer.

3x (x-3)

Final Answer.

I hope this helps!!!!
