Answer:
A
Step-by-step explanation:
![\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3](https://tex.z-dn.net/?f=%5Cfrac%7B%283x%5E%7B2%7D%20%29%5E%5Cfrac%7B1%7D%7B2%7D%20%7D%7B3%5E%5Cfrac%7B1%7D%7B2%7D%20%7D%20%3D3)
![(3x^2)^\frac{1}{2} = 3^\frac{1}{2} x](https://tex.z-dn.net/?f=%283x%5E2%29%5E%5Cfrac%7B1%7D%7B2%7D%20%3D%203%5E%5Cfrac%7B1%7D%7B2%7D%20x)
Remember that
x^(b-c)
Using that
=3^(1/2x-1/2)=3^((x-1)/2)
![3^\frac{x-1}{2} =3^1](https://tex.z-dn.net/?f=3%5E%5Cfrac%7Bx-1%7D%7B2%7D%20%3D3%5E1)
So we can say:
, because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.
1/2 = 0.5
12 & 1/2 = 12 + 1/2 = 12 + 0.5 = 12.5
4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5
Refer to the diagram below. Note how I divided the figure into two rectangles.
The larger red rectangle is 12.5 feet by 10 feet. It has area 12.5*10 = 125 square feet.
The smaller blue rectangle has dimensions 4.5 feet by 5 feet (the 5 is from 15-10 = 5), so it has area 4.5*5 = 22.5 square feet
Now add up those individual areas to get the total area
125+22.5 = 147.5
Then convert that to a mixed number
147.5 = 147 + 0.5 = 147 + 1/2 = 147 & 1/2
<h3>The correct area is 147 & 1/2 feet</h3>
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22
22 + 7 = 29
29 + 8 = 37
sorry that I do not know the equation for this problem...but ur next 3 numbers are : 22,29,37.....so ur answer is D
Answer:
B
Step-by-step explanation:
Fact: The diagonals of a parallelogram bisect each other. If NL= 15 the NP = 1/2 NL
1/2 NL = 15/2 = 7.5.
NP = 7.5
Answer: NP = 7.5 B
Total divided by number of rows=number per row
63/7=9
9 per row
