Numbers can be written in 2 ways –
2023-01-21 13:41:18Numbers are made up of DIGITS (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and can usually be written easily, but speaking and writing with WORDS are difficult You may.
In order to put FIGURES into WORDS, we must assume that this number is in such a PLACE VALUE table.
The correct answer is 4. When x≥2 is a coefficient x 2 - b x + b (b is a constant), x 2 - b x + b can be described as the product (x - 2) (x - a) of real number a. The extension (x - 2) (x - a) is x 2 - 2 x - ax + 2 a and can be rewritten as x 2 - (2 + a) x + 2 a. Therefore, for all values of x, x 2 - (2 + a) x + 2 a = x 2 - b x + b holds. Therefore, the coefficients of the similar terms on both sides of the equation must be the same. 2 + a = b and 2a = b. When this system is solved, 4.b =
Question 13. The selection of D is correct. The numerator of a given expression can be overwritten with denominator x - 3 as follows. x 2 2 x 5 = x 2 3 x + x 3 2 2 This is equivalent to x (x 3) + (x 3) - 2. It is equivalent. Question 14. Selection A is correct. If x is the width of the box (inches), the length of the box is 2.5 x inches. Therefore, the circumference of the base is 2 (2.5x + x) or 7x inches. The height of the box is 60 inches. Depending on limitations, the total of the circumference of the base and the height of the box should not exceed 130 inches. Algebraically, ie 7x + 60≤130, or 7x≤70. Divide both sides of an inequality by 7 to get x≤10. Since x represents the width of the box, x must also be a positive number. Thus, the inequality 0 <x ≦ 10 indicates all tolerances of x that satisfy the given condition.
Different boxes focus on strategies that fit those particular digital sentences. It can be used for strategy examples in the box. • Box # 1 - Double • Box # 2 - Five facts • Box # 3 - Zero and one box # Bit # 4 - Nine - Box # 5 - Square number - Box # 6 - Double and double duplex Box # 7 - Double and one or more sets • Box # 8 - Half, then double circle is the easiest box to complete. Box # 1 Box # 2 Box # 3 Box # 4 Box # 5 Box # 6 Box # 7 Box # 8 Why is it the easiest? # 1 Box # 2 Box # 3 Box # 6 Box # 6 Box # 7 Box # 8 Why is it the most difficult? ________________________________________________________________________________________________________
