a + b - c = 180

add both sides by c

a + b - c + c = 180 + c

simplifying

a + b = 180 + c

subtract 180 from both sides

a + b - 180 = 180 + c - 180

simplifying

a + b - 180 = c

Answer

c = a + b - 180

Use the zero product property to find the solutions to the equation x^2-15x-100=0

7nadin3 [17]

Answer:

$x = 20$ or $x = -5$

Step-by-step explanation:

To solve the quadratic equation we must factor the expression

Look for 2 numbers that when you multiply them, obtain the result -100 and when you add them, obtain the result -15.

You can verify that these numbers are -20 and 5

$-20 +5 = -15\\\\-20 * 5 = -100$

Then the polynomial factors are

$(x-20) (x + 5) = 0$

The zero product property says that if two terms $a * b = 0$ then

$a = 0$ or $b = 0$

$(x-20) = 0$ or $(x + 5) = 0$

$x = 20$ or $x = -5$

Explain why 8 < x < 2 has no solution? need the answer quick

lord [1]

Answer:

8 < x < 2 has no solution because there is no number greater than 8 (8 < x), yet less than 2 (x < 2). It's impossible, so there is no solution.

If the inequality was something like 8 < x < 10, then it will work because 8 can be less than x and x can be less than 10.

Hope this helps and have a great rest of your day! :)
