Answer: There are 4 terms in the Algebraic expression.
Let's call the left side of this tirangle y and downside z.
3² + 6² = y²
y² = 45
y² + z² = (3 + x)²
45 + z² = 9 + 6x + x²
x² + 6² = z²
45 + x² + 6² = 9 + 6x + x²
45 + x² + 36 = 9 + 6x + x²
45 + 36 - 9 = 6x
72 = 6x
x = 12
Answer:
n-5=6
Step-by-step explanation:
five less than a number is represented by n-5 and then it is equal to 6
The second choice
7+ -13= -6
Multiply 3x and -2 by 3 and add 5 to right side of equal sign to get y = -1
