Answer:
número de rancho en casa= 90 homes
número de coloniales = 0
Step-by-step explanation:
Deje que el número del colonial sea x
Deje que el número de rancho sea y
Entonces;
30000 x + 40000 y = 3.6 × 10⁶ ---- (1)
x = 
entonces beneficio P = 30000 x + 8000 y
P = 
Para obtener el máximo beneficio; El número de casas de rancho debe ser lo más alto posible:
número de rancho en casa= 90 homes
número de coloniales = 0
(4x+5)(4x-5) is equal to 16x^2+20x-20x-25
The positive and negative 20x cancel out
Leaving you with: 16x^2 - 25
[S/N this is a pattern that shows up a decent amount. Whenever you have something that looks like (x^2-y^2) it factors out to (x+y)(x-y). It might be helpful to remember]
The next one, (4x+5)2, just follows the distributive property. Multiply both components within the parentheses bye the coefficient of 2: 8x+10
.75 because .75 is .25 from 1.0 and .25 from .5
Answer:
middle
Step-by-step explanation:
Hello here is a solution :
x²-8y-6x+y²=4....(1)
A)
x²-6x = x²-2(3)x+9-9
= x²-2(3)x+3²-9
x²-6x =(x-3)² -9
B)
y²-8y = y²-2(4)y +4²-16
y²-8y = (y-4)²-16
C)
in (1) :
(x-3)² -9 +(y-4)²-16 = 4
(x-3)² +(y-4)² = 29 ...<span>is the standard form of the equation
</span> <span>Select answer 1 :
</span><span>A: 3
B: 4
C: (x−3)2+(y−4)2=29</span>
