Robert is incorrect: Surface are of A is 30 + 30 + 42 + 42 + 35 + 35 = 214 square centimeters. Surface area of B is 120 + 120 + 168 + 168 + 140 + 140 = 856 square centimeters. B's surface area is 4 times as great as A's.
Step-by-step explanation:
y=mx +b
b= 5
12.5= 10m+5
10m = 7.5
m= 0.75
y=0.75x +5
..........
at x= 20 , y= 20
at y= 27.5 , x= 30
at x= 40 , y= 35

Answer:
b=−1/14ot+2
Step-by-step explanation:
Let's solve for b.
to−8+5b=−6+26−9b
Step 1: Add 9b to both sides.
ot+5b−8+9b=−9b+20+9b
ot+14b−8=20
Step 2: Add -ot to both sides.
ot+14b−8+−ot=20+−ot
14b−8=−ot+20
Step 3: Add 8 to both sides.
14b−8+8=−ot+20+8
14b=−ot+28
Step 4: Divide both sides by 14.
14b
14
=
−ot+28
