Answer 1

Відповідь:

50+х больше за 50-х

100-х больше за 10-х

34+х=х+34

х+35 меньше чем 53+х

10+х+10 меньше чем 10+х+20

Answer 3

To compare the given expression without calculating, we can simplify it step by step by combining like terms and grouping them. Let's break down the expression:

50 + x * 50 - x * 100 - x * 10 - x * 34 + x * x + 3490 - x - 20 * 100 - x - 20x + 35 * 53 + x * 10 + x + 10 * 10 + x + 20

Step 1: Group similar terms together:

(50 - x * 100 - x * 10 - x * 34) + (x * x - x - x - 20x) + (50 + 3490 - 20 * 100) + (x + 35 * 53 + x * 10 + x + 10 * 10 + x + 20)

Step 2: Simplify the expressions within each group:

(-84x + 50) + (x^2 - 22x) + (3400) + (x + 1855)

Step 3: Combine all the groups:

x^2 - 105x + 4305

So, the simplified expression is: x^2 - 105x + 4305.

Now, without calculating specific values for x, we can say that the expression is a quadratic function (since it contains x^2), and its graph will be a parabola. The coefficient of x^2 is positive (1), so the parabola will open upwards. The value of x^2 dominates the other terms with x, so the parabola's shape will be mainly determined by the x^2 term. Depending on the specific value of x, the function will either increase or decrease, but it will always be a parabolic curve.
