Answer:
you did it wrong you have to subtract X from 8900.
First you want to subtract 390 from 8900 and that equals
<h2>8510</h2>
For each question we must apply the Pythagorean theorem and clear the value of x.
question 5
x = root (14 ^ 2 + 16 ^ 2)
x = root (452)
x = 2raiz (113)
question 6
x = root (8 ^ 2 + 15 ^ 2)
x = 17
question 7
x = root (12 ^ 2 + 12 ^ 2)
x = root (2 * (12 ^ 2))
x = 12raiz (2)
question 8
x = root (18 ^ 2 - 9 ^ 2)
x = root (243)
x = 9raiz (3)
Answer: -29a-6b+59c
You need to combine like terms
Well suppose you find out that numbers you put in your equation and you solved the equation correctly produces the negative number on your bank account it means nothing except - on your bank account.
