Answer:

Distributive property

Step-by-step explanation:

4(x+3)=4x+12

This example shows distributive property because 4 is distributed (multiplied) to x +3. When 4 is distributed, it will equal 4x+12!!

Hope it helps!!!!

e-lub [12.9K]
To solve this problem you must apply the proccedure shown below:

 1. You have:
<span>
 In(2x+3)=7

 2. Then, you must apply log(e), as below:
</span><span>
 In(2x+3)=ln(e^7)

 3. Now, you obtain:

 2x+3=e^7

 4. Youy must clear the variable "x", as below:

 2x=e^7-3
</span> x=(e^7-3)/2
<span>
 5. Therefore, the value of "x" is:

 x=546.817
</span><span>
 The answer is: </span>x=546.817<span> </span>

What is 6.8 to a fully simplified mixed number
Alisiya [41]
6.8

= 6 + 0.8

= 6 + 8/10 (simplifying...)

= 6 + (8 : 2)/(10 : 2)

= 6 + 4/5

= 6 4/5 <----- this is the answer.

I hope this helps. =)

5x-10y+15z find the equivalent expression by factoring
Marat540 [252]

\huge\boxed{5(x-2y+3z)}

We can divide each term by a factor of 5. 5(1x-2y+3z)

You don't need a coefficient of 1, so simplify that. \boxed{5(x-2y+3z)}

Answer ASAP 84.9 66.2 38.2 33.8
tankabanditka [31]

Step-by-step explanation:

You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.

Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.

sin(\theta)=\frac{o}{h} \\sin(30)=\frac{x}{14} \\0.5=\frac{x}{14} \\x=7

Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.

cos(\theta)=\frac{a}{14} \\cos(30)=\frac{x}{14} \\\frac{\sqrt{3} }{2} =\frac{x}{14} \\x=7\sqrt{3}

This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.

Now you can do the perimeter:

2l+2w\\2(12.124)+2(7)\\24.248+14\\38.25

Your answer is the 38.2
