Length = 2×width -3
or
L = 2w - 3
perimeter = 24 meters
or
p = 24m
p = 2L + 2w
or
24 = 2(2w-3) + 2w ( Remember L = 2w +3)
24 = 4w -6 +2w
24 = 6w + 6
24 - 6 = 6w
18 = 6w
18/6 = w
3 = w
Now that we know ,w, we can find L.
p = 2L + 2w
24 = 2L +2(3)
24 = 2L + 6
24 -6 = 2L
18 = 2L
18/2 = L
9 = L
Now, we can check if the answer makes sense.
p = 2L + 2w
24 = 2(9) + 2(3) (L = 9 & w =3 )
24 = 18 + 6
24 = 24
the answer checks!
Answer:
1. 8 dimes and 7 quarters
2. 14 nickles and 11 pennies
Step-by-step explanation:
Good Luck
For this problem, you need to know the distance formula, as that'll give you the length of the line segment.
Using points A and B, the formula becomes:
Length cannot be negative, so the length of AB is
13.
The answer is -8 i’m sure
Answer:
JUSTIFICATION↓
∠1 ≅ ∠2 <u>(∵ Vertically-opposite angles are equal)</u>
Step-by-step explanation:
Since ∠1 lies vertically opposite to ∠2 and vice -versa , therefore ∠1 and ∠2 are equal to each other
