Step-by-step explanation:
multiply it
x²-3x+3x-9=0
x²-9=0
x²=9
square root both side we get
x=3
The sum of all edges is 108 cm.
There are two bases whose edges are all 8 cm; this gives us 8(4)+8(4) = 32+32=64.
There are 4 edges between bases that are 11 cm each; 11(4) = 44
Together, this gives us 64+44=108 cm.
coefficients are the whole number.
Example : 1x+5x
________ + 15
3x+16x
that's a fraction the coefficients would be the numbers in front of the variable. Variables are the letters in the equation. Which is the x in my equation.
