Answer: =
6x^2−5x−6
Step-by-step explanation: Multiply each term in one expression times each term in the other, then simplify by combining like terms.
Here are the like terms : =(3x+2)(2x−3)=3x(2x+3x(−3)+2(2x)+2(−3)
= 6x^2−9x+4x−6
=6x2−5x−6
The picture in the attached figure
we know that
the total capacity of the storage container=volume of a cone+volume of cylinder
step 1
find the volume of a cone
volume of a cone=(1/3)*pi*r²*h
r=6 m
h=8 m
so
volume=(1/3)*pi*6²*8-----> 301.44 m³
step 2
find the volume of the cylinder
volume of a cylinder=pi*r²*h
r=6 m
h=10 m
s6
volume=pi*6²*10----> 1130.40 m³
total volume=301.44+1130.4-----> 1431.84 m³-------> 1400 m³
the answer is1400 m³
Answer:
x = -6
Step-by-step explanation:
The value of x never changes, no matter what the value of y is, so x = -6 describes every point on the line.
Assuming x=x and y=y in both equations
add them together
-4x+y=6
<u>-5x-y=21 +</u>
-9x+0y=27
-9x=27
divide by 9
-x=3
multiply -1
x=-3
subsiutte
-4x+y=6
-4(-3)+y=6
12+y=6
subtract 12
y=-6
x=-3
y=-6
the soultion set is in (x,y) form
(-3,-6)
