Answer:
343 can be written as

Step-by-step explanation:
since we know,
343 = 7 × 7 × 7
so, we can write 343 as cube of 7
hence,

X/2 >= -4
x >= -4 * 2
x >= -8
The most familiar case is that where you see a " + " sign between two numbers; that's an indication to add the two numbers (or terms) together.
Also, the instruction, "sum up the following," is a command to find the sum of all the numbers that follow.
The factors are (x+3) & (x-2)
Your answer is (x+3)
