Expanding using the distributive property, we get (x-5)*(x-5)=x^2-5x-5x+25=x^2-10x+25. Multiplying that by -6, we get -6x^2+60x-150 . We then add 12 at the end to get -6x^2+60x-138. Using the quadratic formula (since we want the function to equal 0 to find the zeros), we get x=(-60+-sqrt(3600-3312))/(-6*2)=(-60+-sqrt(288))/-12. For sqrt(288), since 12^2=144 and 144*2=288, we can rewrite it as 12*sqrt(2). Putting that back in, we get
(-60+-(12*sqrt(2))/-12. Factoring it out, we get -5+-sqrt(2)=-5+sqrt(2) or -5-sqrt(2) which is C

A 66-meter garden row is divided into 44 equal-sized sections to plant onions.
Gwar [14]
You may represent this multiple ways.

1. 66/44 = m

2. 44m = 66

In both of these scenarios you have a total and equal parts.

The first one starts with a total and breaks it into equal parts.

The second choice shows 44 groups of a part totaling 66 meters.

A sociologist wants to know the opinions of employed adult women about government funding for day care. The women were asked to
Zarrin [17]

Answer:

The correct option is C 20.1%.

Step-by-step explanation:

The probability distribution chart representing the opinions of employed adult women about government funding for day care is as follows:

Rating (<em>X</em>)        Probability (<em>p</em>)

     1                      0.110

     2                      0.206

     3                      0.464

     4                      0.201

     5                      0.119

The ratings are defined as follows:

1: too little

2: helpful but not enough

3: make a difference but insufficient

4: sufficient

5: generous

The probability of women who think that the support is sufficient is, 0.201.

The percentage is: 0.201 × 100 = 20.1%

Thus, the percentage of women who think that the support is sufficient is 20.1%.

The correct option is C.
