Step-by-step explanation:
Hi,
f(x) = (x - 1) - 3
The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)
And the -3 is not embedded with the x, meaning the function will move 3 units down.
I hope this helps :)
Answer:
AREA =18
Step-by-step explanation
think of a rectangle, 12 by 3 which is also 12*3
so you do 12*3=36
but since it is a triangle you have to divide it by 2
36/2=18
18
Answer:
Perimeter: 2(3x+6)+ 2(2x-4)
X=9
Step-by-step explanation:
In order to create the expression you just have to remember that the perimeter of a rectangle equals 2 bases plus 2 sides, so the expression would be:
Perimeter: 2(heights)+ 2(bases)
Perimeter: 2(3x+6)+ 2(2x-4)
IN order to solve for X we just have to insert the value of perimeter, which is 94:
Perimeter: 2(3x+6)+ 2(2x-4)
94=2(3x+6)+ 2(2x-4)
94= 6x+12+4x-8
94=10x+4
94-4=10x
x=90/10
x=9
So the value of x would be 9.

Explanation:
We have:
(
2

(
4

−
5
x
+
6
)
Now let's distribute this piece by piece:
(
2
x
)
(
4
x

)
=
8
x

(
2
x
)
(

(

x
)
=
−
15
x
(

)
(

)
=
18
And now we add them all up (I'm going to group terms in the adding):
8

−
10
x
2
+
12
x
2

And now simplify:
