That would be 15

Because you would do 9-6 first which gives you 3

Then you do 3+12 = 15

Answer:

30cm3

Step-by-step explanation:

Volume=Base area *height

Base area is a triangle=1/2 *base*height

1/2*3*4=6cm2

Height=5cm

Volume=6*5=30cm3

(Answer is below)

Let's solve this step-by-step.

1. Prime factorization of 384.

$=\sqrt{2^7\times3}$

2. Apply the exponent rule. (Formula: $a^b^+^c=a^b\times a^c$ )

$=\sqrt{2^6\times2\times2\times3}$

3. Apply the radical rule. (Formula: $\sqrt{ab} =\sqrt{a}\sqrt{b}$ or $a\geq 0,b\geq 0$ )

$=\sqrt{2^6} \sqrt{2\times3}$

3a. Solve 2 to the 6th power.

$\sqrt{2\times2\times2\times2\times2\times2} =8$

4. Multiply 2 by 3. (Note: Put the 8 in your final answer)

$\sqrt{2\times3} =8\sqrt{6}$

Your answer is: $8\sqrt{6}$

Let me know if you have any questions.

Answer:

Step-by-step explanation:

Exponent law:

$\sf \bf a^m * a^n = a^{m+n}\\\\ (a^m)^n = a^{m*n}$

$\sf a^{-m}=\dfrac{1}{a^m}$

First convert radical form to exponent form and then apply exponent law.

$\sf \sqrt{3}=3^{\frac{1}{2}}\\\\\sqrt{5}=5^{\frac{1}{2}}$

$\sf \left(\dfrac{(\sqrt{3}*3^{-2}}{(\sqrt{5})^2}\right)^{\frac{1}{2}}= \left(\dfrac{3^{\frac{1}{2}}*3^{-2}}{(5^{\frac{1}{2}})^2} \right )^{\frac{1}{2}}$

$= \left(\dfrac{3^{\frac{1}{2}-2}}{5^{\frac{1}{2}*2}}\right)^{\frac{1}{2}}\\\\=\left(\dfrac{3^{\frac{1-4}{2}}}{5}\right)^{\frac{1}{2}}\\\\=\left(\dfrac{3^{\frac{-3}{2}}}{5}\right)^{\frac{1}{2}}\\\\=\dfrac{3^{\frac{-3}{2}*{\frac{1}{2}}}}{5^{\frac{1}{2}}}\\\\ =\dfrac{3^{{\frac{-3}{4}}}}{5^{\frac{1}{2}}}$

What is the solution to the system of linear equations

Alchen [17]

So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.

-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
I hope this helps love! :)
