Step-by-step explanation:
so first what you want to do is split the shape in to
Draw a line down where the 2 is.
you should have a rectangle and a triangle
then you find the area of the rectangle
Rectangle:
5 x 2 = 10m^2
After than you try to find the triangles area
the bottom of the triangle is 9m but since to split it in 2 you will now have 7m
multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2
Add your two areas together and you will get 27.5m^2

Answer:
Step-by-step explanation:
5+ 3(у- 4) = 5(y+2) - у
(expand)
5 + 3y - 12= 5y + 10 -y
(combine like terms)
3y - 7= 4y + 10
(move the variables to one side)
-7 = 4y - 3y + 10
(move numbers to one side)
-7 - 10= 4y - 3y
(simplify)
-17 = y or y = -17
I hope this helps!
