T=10 in 1990. Hope this helps:)
One tenth of something means you have one tenth times something
therefore one tenth of 70000 is one tenth times 70000
1/10*70000=7000
Answer:
We can call the numbers x and x + 1. Then we can write:
x + x + 1 = 113 which simplifies to 2x + 1 = 113.
If the discriminant of a quadratic equation is equal to -8, there are two complex roots.
<h3>Discriminant of a quadratic equation</h3>
The discriminant is used to determine the nature of quadratic equations.
The formula for calculating discriminant is given as:
D = b^2 - 4ac
If the discriminant is negative, it means that the nature of the solution will be a complex number.
Hence if the discriminant of a quadratic equation is equal to -8, there are two complex roots.
