Answer:
x=5
Step-by-step explanation:
4x+5=3x+10
All x values must go on the right so subtract 3x from both sides
4x+5=3x+10
-3x -3x
which gets you
x+5=10
Now subtract 5 from both sides to get the value of x
x+5=10
-5 -5
And you get
x=5
The answer is b. you just multiply the 2 sides of both rectangles to get (6x^2+20x+24) for the bigger rectangle and (x^2-4x+3) for the smaller one so then you substract the bigger one from the smaller one to get the answer
You should first fully understand what an equivalent expression is. This type of expression is an equation that are the same, even though they might look a little different at first glance. When you try to substitute a value to the expression, they will result in the same value at the end.
Happy Studying!
