The product of two consecutive integers is 420 which quadratic equation can be used to find x the lesser number
Fynjy0 [20]

Answer:

If the smallest number is 'x', then the other number = x +1

x*(x+1)= 420

Use distributive property

x*x + x*1 = 420

x² + x - 420 =0   ------> this is the required quadratic equation.

The estimated quotient of 895 divided by 19 is what number?a. 40 b. 45 c. 55 d. 60
Ira Lisetskai [31]

Answer:

b. 45

Step-by-step explanation:

895 ÷ 19 = 47.1

47.1 rounded is 50, but since there is no 50 option, we'll just round it down to 45.

--

another way:

round 895 (900) and 19 (20)

divide:

895 ÷ 20 = 45

you'll get 45 either way :)
