To solve the equation, subtract 3 from both sides. The solution is k = 11.
A linear equation is an equation of which the highest degree of its variables is 1.
Steps to solve linear equations:
- Simplify the expressions. If there are parentheses, remove them by multiplying the corresponding terms.
- Combine the same terms.
- Isolate the variable on one side by using subtraction of addition.
- Use division or multiplication to find the value of the variable.
Recall that if we subtract or add the same number to both sides of an equation, it does not change the equality.
The given problem:
Solve k + 3 = 14.
The variable is k. Subtract 3 from both sides:
k + 3 - 3 = 14 - 3
k = 11 (solved)

Answer:
Step-by-step explanation:
So we have the inequality:
Definition of Absolute Value:
Note that the sign is flipped in the second case because we multiplied by a negative.
Add 5 to both sides to both equations:

Answer:
The storage capacity of the USB is far greater than Kilobytes, but less than a Terabyte.
Step-by-step explanation:
The USB storage device has a capacity of (8 - 256) GB. This implies that the USB has the capacity to store files size from 8 Gigabytes to 256 Gigabytes.
8 Gigabytes ≅ 8 000 000 000 bytes
256 Gigabytes ≅ 256 000 000 000 bytes
Kilobytes would not be an appropriate descriptive measurement of the storage capacity of the USB because 1 kilobyte ≅ 1 000 bytes. Thus;
8 Gigabytes ≅ 8 000 000 kilobytes
256 Gigabytes ≅ 256 000 000 Kilobytes
The storage capacity of the USB is far greater than Kilobytes.
Terabytes can not be used to describe the measurement f the USB because; 1 Terabyte ≅ 1 000 000 000 000 bytes
Thus, the storage capacity of the USB is less than 1 Terabyte.

differnce of 2 perfect squares
a²-b²=(a+b)(a-b)
in this case
x⁴=(x²)²
16=4²
(x²)²-4²=(x²+4)(x²-4)
x²-4 can be factored since 4=2²
x²-2²=(x+2)(x-2)
complete factored form is
(x²+4)(x+2)(x-2)
gegroup to seperate (x+2)
(x+2)[(x²+4)(x-2)]
(x+2)p(x)
p(x)=(x²+4)(x-2)
expanded
p(x)=x³-2x²+4x-8
Answer:
It's the last one. We know it's to the right because the -8 is in the exponent and also, it's -8 not +8.
