Answer:
(2n + 7) (2n +7)
Step-by-step explanation:
To solve this problem we need to factorize 4n^2 + 28n +49 as shown below
thus, after factorization we see that first option is correct one
(2n + 7) (2n +7)
we can validate this by expanding it
2n (2n +7) + 7 (2n+7)\
=> 4n^2 + 14n + 14n + 49 = 4n^2 + 28n +49 (which is equal to the problem stated expression)
Answer:
49/36
here u need to simply multiply and can get the answer! hope you never ask the same question based on it.
Answer:
slope=1
Step-by-step explanation:
because slope=-A/B
slope= -2/-2
slope =1
Answer:
Option D: The area will be multiplied by 16.
Step-by-step explanation:
Given that the area of the figure is 13 sq. in.
Let is say the figure is of dimensions: a & b.
Therefore, a.b = 13 sq. in
When each of the dimension is multiplied by 4, the dimensions would become 4a and 4b.
Therefore, the area would be: 4a . 4b = 16 a . b = 16(13) sq. in.
Hence, the area is multiplied by 16.
