Answer
Expressions 4(x+5) and 5(x+4) are Equivalent
Expressions 5(2m+2) and 10m+10 are not equivalent
Step-by-step explanation:
Heres why,
4(x+5) and 5(x+4)
4 times x =4x, so multiply 4x by 5 which should give you 20.
and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.
5(2m+2) and 10m+10
times 5 to 2m to get 10m and times 10m by 2 to get 20.
10m+10 = 1 which they are not equivalent
I would go with an <span>irrational number because the 0.86421 is a real number and it can't be expressed as a fraction or ratio </span>
S=15
Whatever the number of sides of a polygon,
the sum of its exterior angles is always <span>360∘</span>
Further, each pair of exterior angle and interior angle adds up to <span>180∘</span>
Hence in a polygon with s sides (or angles),
the sum of all the interior and exterior angles would be <span><span>180∘</span>×s</span>
and sum of interior angles would be <span><span>180∘</span>×n−<span>360∘</span>=<span>180∘</span><span>(s−2)</span></span>
As sum of angles is <span>2340∘</span>
Hence, <span>180<span>(s−2)</span>=2340</span> or <span>s−2=<span>2340180</span>=13</span>
and <span>s=13+2=15</span> and polygon is a Pentadecagon.
i hope u understand :)
I think it’s D not sure though
