Answer: 4(7-u)
Step-by-step explanation:
In order to factor, you have to find the GCF (Greatest Common Factor)
28:1, 28, 2, 14, 4, 7
4:1, 4, 2
The greatest common factor here is 4.
You can factor out 4 from this equation, therefore making it 4(7-u)
Answer:
Step-by-step explanation:
The growth rate of the coin is exponential. We would apply the formula for exponential growth which is expressed as
y = ab^x
y = b(1 + r)^ t
Where
y represents the value of the coin after x months.
x represents the number of months.
a represents the initial value of the coin.
b represents rate of growth.
From the information given,
a = 243
b = 1 + 15/100 = 1 + 0.15 = 1.15
Therefore, the exponential expression to determine the number of months, x it will take for the coin to attain a certain value, y is expressed as
y = 243(1.15)^x
If y = 1000, it means that
1000 = 243(1.15)^x
1000/243 = 1.15^x
4.115 = 1.15^x
Taking log of both sides, it becomes
log 4.115 = xlog1.15
0.614 = 0.061x
x = 0.614/0.061
x = 10 months
It will take 10 months
That answer is correct, 9x + 4 -5y. Only like terms are the x terms and we add 3 and 6 together.

Answer:
Base area of box = ![x^2 +4](https://tex.z-dn.net/?f=x%5E2%20%2B4)
Step-by-step explanation:
![Length = 4+x](https://tex.z-dn.net/?f=Length%20%3D%204%2Bx)
![Height = x^2 + 1](https://tex.z-dn.net/?f=Height%20%3D%20x%5E2%20%2B%201)
Base area of a rectangular box is a rectangle
Area of a rectangle (base area)= length times width
![Length = 4+x](https://tex.z-dn.net/?f=Length%20%3D%204%2Bx)
![Width = x](https://tex.z-dn.net/?f=Width%20%3D%20x)
Base area = ![(4+x) \cdot x](https://tex.z-dn.net/?f=%284%2Bx%29%20%5Ccdot%20x)
Multiply x inside the parenthesis
Base area of box = ![4x +x^2](https://tex.z-dn.net/?f=4x%20%2Bx%5E2)
