9 (a - b) + 5 (2a - 2b)
mutiply the first bracket by 9
(9)(a)= 9a
(9)(-b)= -9b
mutiply the second bracket by 5
(5)(2a)=10a
(5)(-2b)= -10b
9a-9b+10a-10b
9a+10a-9b-10b ( combine like terms<em>)</em>
Answer : C. 19a - 19b
The lateral surface area consists of 2 sides with 11 unit long and 4 unit high, and 2 sides with 8 unit long and 4 unit high. Each side is a rectangle. So basically you use area of rectangle to determine the lateral surface area
lat sa = 2 × area of rectangle + 2 × area of rectangle
In this case, it will be
lat sa = (2 × l × h) + (2 × w × h)
lat sa = (2 × 11 × 4) + (2 × 8 × 4)
lat sa = 88 + 64
lat sa = 152
The lateral surface area is 152 squares unit
Answer:
yes
Step-by-step explanation:
Answer:
12.37 square inches
Step-by-step explanation:
The area of the dartboard can be figured from the diameter as ...
A = (π/4)d² = (π/4)(17.75 in)² ≈ 247.4495 in²
There are 20 sectors, all the same size, so the area of one of them is ...
sector area = (1/2)(247.4495 in²) ≈ 12.37 in²
