Il perimetro di un rettangolo è 126 cm. La base è i tre quarti dell'altezza. Mi potreste dire come procedere?
1 answer:
Answer:
w = 36 cm
L = 27 cm
Step-by-step explanation:
I am translating and I see that perimeter of rectangle is 126 cm and the base (assuming Length) is (3/4) the height.
P = 2(l+w)
Divide both sides by 2, so you get
(3/4)w+(4/4)w=(126/2)
(7w/4)=63
Multiply both sides by 4,
7w=252, then divide both side by 7,
w = 36, Width is 36 cm, so Length is (3/4), which is L = 27 cm

Acceleration is rate of change of velocity.
<em>a = acceleration ( m/s² )</em>
<em>v = final velocity ( m/s )</em>
<em>u = initial velocity ( m/s )</em>
<em>t = time taken ( s )</em>
<em>d = distance ( m )</em>
Let us now tackle the problem !

Answer:
Step-by-step explanation:
The first expression is
The sum of the constants is 7+3=10
The sum of the coefficients is 3+7=10
The second expression is;
The sum of the constants is 7+1=8
The sum of the coefficients is 4+4=8
The third expression is;
The sum of the constants is 8+2=10
The sum of the coefficients is 4+8=12
The fourth expression is;
The sum of the constants is 8+4=12
The sum of the coefficients is 3+7=10
Hence the correct choice is the expression in which the sum of the constants greater than the sum of the coefficients
