Answer:
2000 + 600+ 2
Step-by-step explanation:
expanded form is: way to write a number by adding the value of its digits
49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
Answer:
4(2x+7) which is equal to 8x+28
What following are you choosing from
2n=16 divide both sides by 2 you get n=8
