Use distrubutive property <em>a(b + c) = ab + ac</em>
6(5r - 4) - 2(r - 7s - 3)
= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)
= 30r - 24 - 2r + 14s + 6
= (30r - 2r) + 14s + (-24 + 6)
<h3>= 28r + 14s - 18</h3>
Answer:
1200 centimeters
Step-by-step explanation:
if you have 100 centimeters in 1 meter and there are 12 meters you can just multiply the number of centimeters by 12 or whatever number is needed in this case 12 so when you multiply 12 x 100 you get 1200

Answer:
Perimeter of the square field is 600 meters.
Step-by-step explanation:
Given:
Area of a square field = 2.25 hectares
1 hectare = 10000 m²
∴2.25 hectares = m²
Now, let each side length of the square field be meters.
∴ Area =
⇒
⇒ m
Now, perimeter of a square is given as, .
Here, m.
∴ m
Hence, the perimeter of the square field is 600 meters.
