A) multiple the 3 x 4 and add 1.
3 x 4 = 12 + 1 = 13
13/3
B) (7 x 3) + 2 = 23/3
C) (4 x 2) + 1 = 9/2
D) (2 x 8) + 7 = 23/8
ITS A i jus did it its bot be or c or d
3. 17-H
4. H-17
5. m•4 or 4m
6. 2(3)+ 5 (to the second power) - 3(6)-4(1)
which equals : 9
So u need to find the circumference of the half circle by finding the circumference of the whole circle and dividing by 2 so that gives you 12.565 then u find the perimeter of the rectangle but not the 4th side cause that’s on the inside when u do that u get 10+10+8 which is 28 then add the half circle and I get 40.565 ft but round to nearest hundred so 40.56 ft
