You want to use PEMDAS to solve this problem.
So we do the parentheses first (4-2) = 2
Then you would do the exponent next
2 to the 5th power is 32
2 to the 3rd power is 8
(2) to the 4th power is 16
32 / 8 • 16
Then we want to do Multiplication and division from what ever comes first so in this case 32/8, which will equal 4 then we multiple 4 with 16 making the answer 64
Hey there!!!
Equation given :
p ( x ) = 3x² + 4x + 5
Find p ( 2x )
In order to solve this, we will have to substitute the value 2x instead of x
Hence,
... p ( 2x ) = 3 ( 2x )² + 4 ( 2x ) + 5
... p ( 2x ) = 3 ( 8x² ) + 8x + 5
... p ( 2x ) = 24x² + 8x + 5
As we know I ( x ) = p ( 2x )
The value of I(x) = 24x² + 8x + 5
Hope my answer helps!
I can't see pictures T^T.
To find the are of a triangle, you multiply the dimensions as you would a rectangle, but divide the product by 2.
Example:
The dimensions of triangle B are 4 and 9.
4x9=36
Now divide.
36/2=18
So the area of triangle B is 18.

Answer:a) mean=167.1
b)median=168.5
c)mode= 180
Step-by-step explanation:
Mean= total sum of values in the data set/ number of values
=2339/14=167.1
Median = midpoint = 165+172/2= 337/2= 168.5
Mode= number with the highest number of frequency, for this data set, 180 occurred most because it occurred three times
