Answer:
Step-by-step explanation:
The discriminant is what's under the square root sign in the quadratic equation. The equation for the discriminant is , where b is the coefficient of x, a is the coefficient of , and c is the number with no variable attatched to it. If we plug in the numbers () it gives you 241, which is the discriminant. Since 241 is more than zero, it has 2 zeros. If the discriminant was 0, there'd be 1 zero, and less then zero there would be zero zeros.
To solve the exercise, let us first draw the rectangle:
The formula to find the area of a rectangle is
So, in this case, you have
On the other hand, the perimeter is the sum of all the sides of a geometric figure. Then, in this case, you have
Therefore, the perimeter and area of this rectangle are:
Required: 10
8+5=13
How to get 10:
13-10=3
Therefore, in order to get 10 from the sum of 8+5, you must subtract 3.
All 4 sides of the square patch are of the same length and the area is side squared so to find the length of each side,just squareroot 36m.The ans is 6m.
