Answer:
x=1
Step-by-step explanation:
5x+2=3x+4(2x-1)
First take the ( ) 4*2xand 4*-1
Then simplify and add all like terms
then subtract/add(opposite of what it is) whichever x term from both sides
then subtract/add the numbers on the side you chose to the other side to get something as the following
x=#
then divide x by the #
The area of the rhombus and trapezoid from the figure are 2 square in and 5 square in respectively
<h3>How to find the area of a trapezoid and rhombus?</h3>
The given pattern consists of rhombus and trapezoids
The formula for calculating the area of rhombus is expressed as:
A = pq/2
Area of trapezoid = 0.5(a+b)h
Given the following
height = 2in
a = 2in
b = 3in
Ara of rhombus = 1(4)/2 = 2 square inches
Area of the trapezoid = 0.5(2+3) * 2
Area of the trapezoid = 5 square inches
Hence the area of the rhombus and trapezoid from the figure are 2 square in and 5 square in respectively

Answer:


Step-by-step explanation:
we have
-----> equation A
----> equation B
To find the solutions for x of the system of equations
equate equation A and equation B

The values of x of the intersection points are the solutions of the system
Using a graphing tool
see the attached figure
There are two intersection points
therefore
The solutions are
