This is an addition problem.
Rearrange the given equations as
<span>+ f(x)=5x-2
+g(x)=2x+1
----------------
Add up each column, as follows: (f+g)(x) = 7x - 1 (answer)</span>
Answer:
In the procedure
Step-by-step explanation:
we have
<em>System 1</em>
Ax+By=C -----> equation A
Lx+My=N -----> equation B
<em>step 1</em>
Multiply equation B by -1 both sides
(-1)*(Lx+My=)N*(-1)
-Lx-My=-N ------> equation C
<em>step 2</em>
Adds equation A and equation C
Ax+By=C
-Lx-My=-N
----------------
Ax-Lx+By-My=C-N
(A-L)x+(B-M)y=C-N -----> equation D
step 3
An equivalent system (System 2) is formed with
Ax+By=C -----> equation A
(A-L)x+(B-M)y=C-N -----> equation D
Answer:
Step-by-step explanation:
2(x-1)=50, lets multiply
2x-2=50 add 2 in both sides
2x=48
x=24
your options are weird, unless you mean (x-1)^2 ?
The area of the circle whose circumference is equal to the perimeter of the square is 38.47 squared units.
<h3>What is circumference and area of the circle?</h3>
Circumference of the circle is the length of its boundary. It can given as,
The area of the circle is the space occupied by it. It can be given as,
Here (<em>r</em>) is the radius of the circle.
A square has a side that measures 5. 5 units. The perimeter of the square is the equal to the 4 times of its side. Thus its perimeter is,
The circumference of the circle is equal to the perimeter of the square. Thus the radius (<em>r</em>) of circle is,
The area of this circle is,
Hence the area of the circle whose circumference is equal to the perimeter of the square is 38.47 squared units.
