You are adding 6 to each number. (N-1)+6, I guess
Combine numbers with the same variable so 10a + 7a = 17a and 3b + 6b = 9b. So the full answer is 17a + 9b.
To cover the toy box 35.475 sq ft paint is needed.
Step-by-step explanation:
Given,
The length (l) of the toy box = 3.8 ft
Width (w) = 2.65 ft
Height (h) = 2.75 ft
To find the amount of paint is need we need to find the lateral surface area first.
Formula
Lateral surface of the box = 2(l+w)×h
Now,
The surface area of the box = 2(3.8+2.65)×2.75 sq ft
= 35.475 sq ft

Answer:
The cost of the pillar is $22,947.12
Step-by-step explanation:
Diameter of the pillar = 6m
Radius = diameter / 2 = 6 / 2 = 3m
Height if the pillar = 7m
Volume of the pillar = πr²h
π = 3.14
V = 3.14 × 3² × 7
V = 3.14 × 9 × 7
V = 197.82m³
Volume of the pillar is 197.82m³
If 1m³ = $116
197.82m³ will cost $x
X = (197.82 × 116) / 1
X = $22,947.12
The cost of the pillar is $22,947.12
