2c=14 (move 5 to the other side by adding it to 9)
c=7 (divide by 2 to get c on its own)
Answer:
10: 12 units^2 11: 33 units^2
Step-by-step explanation:
10:
Divide into square and 2 triangles (for simplicity)
square=9
one triangle=3/2
both triangles combined=3
9+3=12
11:
divide into 2 triangles
top triangle: height= 4, base=6
bottom triangle: height= 7, base=6
top=12
bottom=21
Add, 33.

Answer:
D - 72
Step-by-step explanation:
32 divided by 4 is 8.
So 8 times 5 is 40.
32 plus 40 equals 72.
Area=lenght times widht
area/length=width
(4x²+12x)/(4x)=width
we can factor out the 4x
4x²+12x=4x(x+3)
so the width is x+3
