Answer:
x=8 or x=-2
Step-by-step explanation:
x²-16=6x
x²-6x-16=0
x²-8x+2x-16=0
x(x-8)+2(x-8)=0
(x-8)(x+2)=0
either,. or.
x-8=0 x+2=0
x=8 x=-2
Answer:1490
Step-by-step explanation:so while solving this question, you want to make sure the decimals are on top of each other. 8+8 is 16 so you write 6 and carry 1. 4+9 is 13 +1 =14, write 4 carry one across the decimals. 5+4 is 9 plus 1 equals 10 write zero carry 1. 7+1 is 8 plus 1 is 9 so you write that down and since 1 and 4 have no numbers under them, you write it down too giving you 1490.46
