No because u have to have 9 or 9 or 8 and 8
These triangles are not congruent. They only have 2 sides and one angle in common, and that is not a congruency theorem.
Answer:
Remainder
Step-by-step explanation:
When a number can't be divided equally, there's an amount leftover. The leftover number is called a <em><u>remainder</u></em>
I'm not really great at explaining stuff, but I hope this helps!
Answer:
Step-by-step explanation:
Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24
