width (w) = w
Length (L) = 3w + 4
Area (A) = L x w
25 = (3w + 4)w
25 = 3w² + 4w
0 = 3w² + 4w - 25
w = 
w ≈ 2.3, w ≈ -3.6 (width cannot be negative!)
w ≈ 2.3
Length (L) = 3w + 4 = 3(2.3) + 4 = 6.9 + 4 = 10.9
Answer: width=2.3, Length=10.9

Answer:
P = 50,000
r = 0.08
i = 0.02
K = 4
n = 20
t = 5
Step-by-step explanation:
In this formula, r is the annual interest rate, 8% or 0.08. K is the number of times the interest is compounded in a year. Since interest is compounded quarterly, K = 4.
r = 0.08
i = r/K = 0.08/4
i = 0.02
t is the number of years interest is compounded, so ...
t = 5
n = Kt = 4·5
n = 20
P is the principal amount invested:
P = 50,000
<h2><u>solución</u></h2>
deja que los números sean x, and x + 2
sabemos que su suma es igual a 100, entonces
por lo tanto, el primer número es 49
y el segundo número es x + 2 = 49 + 2 = 51 (también es el mayor entre los dos números)
entonces suma de dígitos de mayor número = 5 + 1 = 6
Respuesta correcta de la pregunta anterior = 6
Answer:
ABOUT 13 PERCENT
Step-by-step explanation:
I AM NOT CERTAIN BUT I GOT IT BY:
NEW PRICE - OLD PRICE divided by OLD PRICE X 100
