First you must know that is i∧2= -1
x∧3-4x∧2+4x-16 = x∧2 (x-4) + 4 (x-4) = (x-4) (x∧2+4) = (x-4) (x∧2-(-4)) =
= (x-4) (x∧2-(-1) *4) = (x-4) (x∧2- i∧2*2∧2) = (x-4) (x∧2-(2i)∧2) = (x-4) (x-2i) (x+2i)
Good luck!!!
The number that is being multiplied by the variable ( the letter) so like if you have 2X the 2 is the coefficient
Answer: 7 is 3216.99cm²
7 part b is 24.31 rounded the answer is 24.
The quilt would be 1.13 yards wide
X = 56 degrees because the sum of all the angles in a triangle is 180 degrees.
