pogonyaev

Answer:

7

Step-by-step explanation:

hi , you can see here we have a rectangle without a triangle :

area rectangle - area  triangle = area of the shape

Area of the triangle= L x l

=4 x 2

=8

Area of the triangle = \frac{b X h}{2}

=\frac{2 X 1}{2}

=1

So we do :   8 - 1 = 7

I hope it is gonna be helpful,

have a nice day.

Question Solve for x 3x = x + 8​
Viktor [21]

Answer:

x=4

Step-by-step explanation:

here's our equation: 3x=x+8

Our goal: to isolate x onto one side with nothing else on that side.

x is on both sides; we can subtract x from both sides to make the variables and numbers be on different sides

2x=8

Now we can divide by 2

x=4

Hope this helps! :)
