The answer is 4 because 2--2 the two negatives make it a positive so its 2+2=4
289 X 7 = 2023
2022 2023 2024
2023 IS BETWEEM 2022 AND 2024 (:
• Expand (2a + b)²:
(2a + b)²
= (2a + b) · (2a + b)
Multiply out the brackets by applying the distributive property of multiplication:
= (2a + b) · 2a + (2a + b) · b
= 2a · 2a + b · 2a + 2a · b + b · b
= 2²a² + 2ab + 2ab + b²
Now, group like terms together, and you get
= 2²a² + 4ab + b²
= 4a² + 4ab + b² <——— expanded form (this is the answer).
I hope this helps. =)

I’m not sure about the rest but the slope is 4 and the y intercept is 3.
I hope this helps you
