The letter x has two lines of symmetry.
So it is asking you to group like term so
x terms can be grouped/added/subtracted to other x terms, but not to x^2 or x^3 terms
x^2 terms to x^2 and so on so
1. 9-3k+5k=
9+(5k-3k)=
9+2k
2. k^2+2k+4k=
k^2+(2k+4k)=
k^2+6k=
16 cm.
This is because one side of the hexagon is half of one side of the square. Therefore, you multiply 8 by 2. 8x2 = 16
215% of 18
You must change 215% into a decimal by multiplying by 100 which is 2.15
Then you multiply them
2.15×18=38.7
Then you estimate to the nearest whole number
38.7⇒39
You answer is 38.7
Your answer is 39 estimated
Answer:
the value of x is 13 because 2 times 13 equals 26 and 26 plus 6 equals 32.
