Answer:
l = 7 in; w = 3 in
Step-by-step explanation:
The formula for the area of a rectangle is
A = lw
Data:
A = 21 in²
l = w + 4
Calculation:
21 = (w + 4) × w
21 = w² + 4w
w² + 4w - 21 = 0
(w + 7)(w - 3) = 0
w + 7 = 0 w - 3 = 0
w = -7 w = 3
We reject the negative value, so w = 3 in.
21 = l × 3
l = 7
The rectangle is 7 in long and 3 in wide.
Answer:
4) 3.5
5) -1.375
Step-by-step explanation:
plug in x for the missing number and solve
Answer:
Well to this you would have to simplify the ratio first
75:35:45
That can be
15:7:9
So that means thayt each troop would get 15 enegery bars, 7 drinks and 9 bottles of water
Well if you were to keep repeating that process or just do a proportion you would get 5 total troops.
15:7:9
75:35:45
15*5 is 75
7*5 is 35
9*5=45
So 5 troops
What are you trying to ask? Are you saying a family eats 1 bread 2 bread 3 bread each meal which combination will allow for 2 meals?
If so it’s 1 and 2 if your saying they eating 1 2 3 bread each meal 3 isn’t enough
