The perimeter is the sum of the outside dimensions.
b1 = 87 - 32 - 14 - 13 = 28 in.
Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.
Divide area by the amount 1 can covers:
360 / 50 = 7.2 cans, round up to 8 cans are needed.
Answer:
C and E
Step-by-step explanation:
I know how to do this, please mark brainliest
So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2
Answer:
-18
Step-by-step explanation:
g(x)=-5x+2
g(4)=-5(4)+2=-20+2=-18
Answer:
-2/3
Step-by-step explanation:
We need to pick two points on the line.
(-2,0) and (1,-2)
We can use the slope formula
m = (y2-y1)/(x2-x1)
m = ( -2-0)/(1 - -2)
= (-2-0)/(1+2)
= -2/3
