Gruop x terms
(x²-8x)+3=0
take 1/2 of linear coefient and square it
-8/2=-4, (-4)^2=16
add negative and positive inside
(x²-8x+16-16)+3=0
factor perfect square
((x-4)²-16)+3=0
expand
(x-4)²-16+3=0
(x-4)²-13=0
add 13 both sides
(x-4)²=13
answer is C
Answer: B. 4
Step-by-step explanation: Divide 20 by 5 and get 4.
Well, 2/10 times 5 is 1; therefore, there will no more pie left because it has already been dispersed completely.
However, if this is a trick question, there is 100% of the pie left because even though it is on their plate, they haven't eaten it. If its not a trick question, ignore this.
Answer:
x = 14/3
Step-by-step explanation:
9.
The given equation is:
(x-2)+(x-3)+(x-9)=0
After opening the brackets,
x-2+x-3+x-9=0
3x+(-2-3-9) = 0
3x-14=0
x = 14/3
So, the value of x is equal to 14/3.
