Answer:
2x^4 + x^3 - 2x -1
Step-by-step explanation:
Do each one at a time and add them after you are done is necessary, first multiply 2x times x^3 this gives 2x^4. Then multiply 1 times x^3 to get x^3. Then multiply 2x times -1 to get -2x. Then multiply -1 and +1 to get -1. Then combine them together. None of the terms are like terms so you don't need to worry about combining them further but keep that in mind for other problems. The final answer becomes 2x^4 + X^3 - 2x -1 because none of the terms are the same power.
X = 35
Step 1: Multiply both sides of the equation by seven thirds
Step 2: Reduce sides
Step 3: Multiply the numbers
Answer:Number Sets. There are sets of numbers that are used so often they have special names and symbols: ... The numbers you can make by dividing one integer by another (but not dividing by zero). In other words ... If you square a real number you always get a positive, or zero, result. ... x + 7 = 0, x = −7, Integers, set integer.
Step-by-step explanation:
Answer:
4x + (5x+18) = 180-81=99
9x+18=99
9x=99-18=81
x=9
Step-by-step explanation:
1. plug in the numbers for the variables, like this: 9(-5)+18(-1)
2. solve
