Answer:
y^2 +8y + 16
Step-by-step explanation:
6y^2 +2y +5 - (5y^2 -6y -11)
I distribute the minus sign
6y^2 +2y +5 - 5y^2 +6y +11
Then I put them vertical.
6y^2 +2y +5
-5y^2 +6y +11

y^2 +8y + 16

Answer:
704 cm
Step-by-step explanation:
The two triangles are 8x12=96 and since there are two triangles 96x2=192.
Next you do the top and bottom rectangles 10x16=160 and the two rectangles are the same size so 160x2=320.
Now you do the middle rectangle 16x12=192.
Now you add all the areas together 192+320=512+192=704cm.
So the answer is 704 cm!
