Answer:

  • left box: 25/36
  • right box: 5/6

Step-by-step explanation:

If you square the binomial (x -a), you get ...

  (x -a)² = x² -2ax +a²

Comparing this to your equation, you find that ...

  -2a = -5/3 . . . . . . the x-coefficient

  a = (1/2)(5/3) = 5/6

So, the number in the right box is 5/6, and the number in the left box is its square, (5/6)² = 25/36.

Filling these in, the equation reads:

  x² -5/3x +25/36 = (x -5/6)²

__

That is, the constant in the squared binomial is half the x-coefficient.

Find the distance CD rounded to<br> the nearest tenth.<br> C = (7,-4) and D = (-8,-5)<br> CD = [?]
quester [9]

Answer:

CD= 15.03

Step-by-step explanation:

x1=7, x2= -8

y1=-4, y2=-5

distance CD= √(x2- x1) 2+ (y2-y1)2

= √( -8-7)2 + [-5-(-4)]2

= √(15)2+ (-5+4)2

= √225+ (1)2

= √225+1

= √226

= 15.03

Which of the following is NOT equivalent to 240/300
Lyrx [107]
Two fractions are said to be equivalent if both the numerator and the numerator of one fraction can be obtained by multiplying or dividing the numerat.or and denominator of the other fraction by a single factor.

Dividing the numerator and denominator of 240/300 by 5 gives 48/60
Dividing the numerator and denominator of 240/300 by 60 gives 4/5
Dividing the numerator and denominator of 240/300 by 10 gives 24/30

Whereas dividing 300 by 2 gives 150 dividing 240 by 2 will not give 122. so 122/150 is not equivalent to 240/300.

Justify each step in solving the equation 6x = 3 (x + 4) by writing a reason for each statement.
BaLLatris [955]
First thing is to multiply 3 by x and get 3x,then 3 by 4 equals 12. 3x+12....6x=3x+12...subtract 3x from 6x and get 3x=12..then divide 3 on both sides and 3x crosses out.. and x=4...this is what I have to say about this..
