40! / 30! = 40*39*38*37*36*35*34*33*32*31
dividing this by 10! 10*9*8*7*6*5*4*3*2*1
= 4*13*19*37*17*11*4*31
= 847,660,528
Answer:
Option B is correct.
Step-by-step explanation:

We need to write the above equation in square root form.
We know that 1/4 = ![\sqrt[4]{x}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%7D)
So,
can be written as:
![(\sqrt[4]{10})^{3x}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B10%7D%29%5E%7B3x%7D)
Option B is correct.
In this question, you're solving for d.
Solve for d:
5(-6 - 3d) = 3(8+7d)
Use the distributive property:
-30 - 15d = 3(8+7d)
-30 - 15d = 24 + 21d
Add 30 to both sides:
-15d = 54 + 21d
Subtract 21d from both sides
-36d = 54
Divide both sides by -36
d = -3/2
Answer:
d = -3/2 or -1.5
Answer:
<u>144</u>
Step-by-step explanation:
Ok. I love problems like this.
You just have to find the surface are of each part and add it up!
To find the surface area of a rectangle, you multiple the base and the height. To find the surface area of a triangle, you multiple the base and height, and divide by 2 (because its half of a rectangle).
<u>Left rectangle:</u> 3*ll=33
<u>Middle rectangle:</u> 4*ll=44
<u>Right rectangle:</u> 5*ll=55
<u>Top triangle:</u> 3*4=12
12/2=6
<u>Bottom triangle:</u> 3*4=12
12/2=6
<u>ADD THEM ALL!!!</u> 33+44+55+6+6=<u>144</u>
