Its 1,000 because its 981 right so you have to use a line so you'll see where 981 is.
45÷5 is 9 so that means joe has only 9 marbles
So length is 3.9 cm more than 3 times the width
perimeter is 32.6 cm
l = 3w + 3.9
P = l + l + w + w
32.6 = 3w + 3.9 + 3w+ 3.9 + w + w
combine like terms
32.6 = 7.8 + 8w
subtract 7.8 from both sides
24.8 = 8w
divide both sides by 8 to isolate w
3.1 = w
so we solved that the width is 3.1 cm
to find the length
l = 3.9 + (3*3.1)
l = 3.9 + 9.3
l = 13.2
The dimensions:
Length is 13.2 cm
Width is 3.1 cm
Hope this helps :)
Answer:
- 2⁻⁶
Step-by-step explanation:
To simplify this we have to know the following rules.
(i) (xᵃ)ᵇ = xᵃᵇ
(ii) 1/xᵃ = x⁻ᵃ
Given: 
= 
= 
= 
[using (i)]
= 
[using (ii)]
Hence, the simplified form would be:
