Answer:
5
Step-by-step explanation:
if ax^2 +bx + c ====>discriminant formula is b^2 - 4ac from the quadratic formula
x2 + 3x + 1 = 0
Then;
a=1
b=3
c=1
b^2 - 4ac = 3^2 -4*1*1
= 9-4
= 5
Regrouping in addition, as in 64 + 43, involves adding numbers column by column from right to left. If the addition in a column results in a value of 10 or more, a 'carry over' or regrouping is done to the next column. The final resultant sum is 107.
To regroup when you find the sum of 64 + 43, you need to add the numbers column by column, moving from right (units) to left (tens, hundreds, etc.). In this case, add the right column (4 from 64 and 3 from 43) to get 7. Next, add the left column (6 from 64 and 4 from 43). The sum is 10. Since 10 is a two-digit number, the number in tens place (1) is carried over or regrouped to the tens column. To get the final answer, add the numbers in the tens column (including the carryover). This results in 107. In general, regrouping is a technique used in addition and subtraction to simplify calculations and solve problems more easily.

For this case we must factor the following equation:
It is observed that both terms contain the variable "d", so we can take it out as a common factor:
On the other hand, we look for the factors of 36 and 121:
36: 1,2,3,4,6,9,12,18,36
121: 1, 11,121
The greatest common factor between both numbers is 1.
Thus, the expression is factored as:
Thus, one of the roots of the polynomial is 0.

Answer:
Step-by-step explanation:
Given: The number of days Jonathan ran = 5
The most he ran in 1 day = 3.5 miles
Therefore, the maximum distance he ran in a week=
Let x be the distance Jonathan could have rum in a week, such that
Hence, the required inequality is .
