Your answer is A=1.2(2x+3)
Answer:
A simplified version of “<u>–7c8·(–0.4c3)2</u>,” would be,
“<u><em>–7c8·(–0.4c3)²= (-7c8)(-0.4)²(c)^6</em></u>”

Since they want the unit of volume to be cm^3, first we have to convert the values given from inch into cm
=> 12 in = 30.48cm
4 in = 10.16cm
14 in = 35.56cm
Since both of the figures are cylinders, we have to find them one by one
Find the volume of the upper cylinder
Formula: V = pi*r^2*h
We know, pi = 3,
radius = diameter of base/2
=> r = 30.48cm/2 = 15.24cm
height = 30.48cm
We get V=3*(15.24)^2*30.48=21237.6cm^3
Find the volume of lower cylinder
Formula: V = pi*r^2*h
We know, pi = 3,
radius = diameter of base/2
=> r = 35.56cm/2 = 17.78cm
height = 10.16cm
We get
V = 3*(17.78)^2*10.16 = 9635.6cm^3
Therefore, the volume of the object is
V = 21237.6cm^3 + 9635.6cm^3
= 30873.2cm^3.
The simplified product of 
and -3
is -30
.
Given Two expressions: -3 and 2
.
We have to multiply both the expressions and it can be done as under:
-3 *2
Firstly we have to multiply -3 with 2 to get
=-6
Then we have to find square root of x cube and x square which is x to the power 3/2 and x to the power 1.
=
Now we have to multiply both the numbers in the root to get the answer;
=-6
Square root of 50 is 5 root 2.
=-6*5
=-30
Hence the simplified product is -30.

Answer:
23
Step-by-step explanation:
First of all substitute x with g(x) on the expression of f(x)
; (f.g)(x) = -4(2x - 6) + 7
; (f.g)(x) = -8x + 24 + 7
Then substitute the value of x with the value 1...as the question asks yu
; (f.g)(1) = -8(1) + 24 + 7
; Hence (f.g)(1) = 23
