Find the product. (n + 4)2
2 answers:
Answer:
2n+8 or if the 2 is an exponent
Step-by-step explanation:
The Distributive property says a(b+c)=ab+ac
Knowing this, lets apply it to the problem...
1) Distribute 2 to n:
2n
2) Distribute 2 to 4:
2n+8
If the problem is squared, use foil (first, outer, inner, last)
(n+4)(n+4)
n^2+4n+4n+16
1) Simplify:
n^2+8n+16

F you just want to see the really short way, just skip down to AAAAAAAAAAAA
so, here is the long explanation
exponential properties
don't forget pemdas
2x^2=2(x^2)
so
=
AAAAAAAAAAAAAAAAAAAAAAAA
so we see
the original equatio is
remember
so we can seperate the constants
we know that the placeholders cannot affet the position of the constants unless they are grouped together which they are not
terfor the answer must have 2/3 in it
the only one that hsa that is A

Answer:
x = 41.2
Step-by-step explanation:
Assuming the dotted line at the top is parallel to the segment with length x, it follows from the alternate interior angles theorem that the interior angle of the triangle (marked in diagram) is also 27º.
Using SOH-CAH-TOA, we get that tan(27º) = 21/x, so x = 21/tan(27º), which is approximately equal to 41.2.
