Answer:
Step-by-step explanation:

Using the quadratic formula:

Since the discriminant is negative, -31, there are no real roots
The value of x=20
Step-by-step explanation:
We need to find the value of x
We are given a right angle which is equal to 90°
So, all three angles must sum to 90°
Our equation will be:

Solving and finding value of x

So, the value of x=20

204 902.0
124 510.0
Move the decimal point to the left, until you have a number less than 10.
204 902 = 2.04902 × 10⁵
124 510 = 1.2451 × 10⁵
12a-(4b+4a)-b
12a-4b-4a-b
=> 8a-5b
