1.Given the quadrilateral ABCD with two diagonals perpendicular and AB = 8cm, BC = 7cm, AD = 4cm. Evaluate CD.
2.Given three consecutive even natural numbers, which have the product of last two numbers is 80 greater than the product of first two numbers.
Find the largest number.
Answer: The largest number is
2) đặt 3 số có dạng a; a+2, a+4 rồi khai triển ra
số lớn nhất là 22
Given three consecutive even natural numbers, which have the product of last two numbers is 80 greater than the product of first two numbers.
Find the largest number.
(x + 1)(x + 2) - x(x + 1) = 80
(x + 1)(x + 2 - x) = 80
(x + 1)2 = 80
x + 1 = 40
=> x = 39
=> x + 2 = 39 + 2 = 41
Vậy số lớn nhất là 41.
ngồi phán đề nên ko biết dịch đúng ko, làm sai thì đừng chửi nhá
Đề bài : cho 3 số tự nhiên liên tiếp. Tích 2 số đầu cuối lớn hơn tích 2 số đầu là 80.
Gọi 3 số tự nhiên liên tiếp là a (a + 1) (a + 2).
Ta có (a + 1)(a + 2) = a(a + 1) + 80
=> (a + 1)(a + 2) - a(a + 1) - 80 = 0
=> a2 + 3a + 2 - a2 - a - 80 =0
=> 2a - 80 = 0 => a = 40
Vậy số lớn nhất là a + 2= 40 +2 =42
