Answer:
4(x+4)
Step-by-step explanation:
Find to GCF of 4x+16.
Now factor out the GCF by dividing each term in the expression by 4.
4x divided by the GCF is x, and 16 divided by the GCF is 4.
The equivalent expression is 4(x+4).
Answer:
9 square inches is your answer. √9=3
If the two diagonals are
and
, the are of the rhombus is

So, in your case, the area is

The other options are wrong because:
- option A doens't divide by 2, thus getting twice the area of the rhombus
- option B summed the diagonals instead of multiplying them
- option D took the difference of the diagonals.
Answer: x^2+8x+16
Step-by-step explanation:
Following (a+b)^2=a^2+2ab+b^2,
(x+4)^2=x^2+2(4x)+(4)^2
x^2+8x+16
