Solve for t. t + 19 = 45) it will give u 29 points if u help me!
Oksi-84 [34.3K]

Hi there!

<u><em>Answer:</em></u>

<u><em>t=26</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

First, you subtract by 19 from both sides of an equation.

t+19-19=45-19

Then, you subtract by the numbers from left too right.

45-19=26

<u><em>Final answer is t=26</em></u>

I hope this helps you!

Have a nice day! :)

Solve the following quadratic equation<br>5х2 - 10x – 21 = 39​
-BARSIC- [3]

Answer:

x=1+√13 or x=1−√13

Step-by-step explanation:

Step 1: Subtract 39 from both sides.

5x2−10x−21−39=39−39

5x2−10x−60=0

For this equation: a=5, b=-10, c=-60

5x2+−10x+−60=0

Step 2: Use quadratic formula with a=5, b=-10, c=-60.

x=

−b±√b2−4ac

2a

x=

−(−10)±√(−10)2−4(5)(−60)

2(5)

x=

10±√1300

10

x=1+√13 or x=1−√13
