<u>The error is that they had placed the numbers in the wrong placeholder.</u> Remember that the Distance formula is D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} .

<em><u>Correct Work:</u></em>

D=\sqrt{(5-(-1))^2+(16-15)^2}\\D=\sqrt{6^2+1^2}\\D=\sqrt{36+1}\\D=\sqrt{37}\ \approx 6.08

Solve the equation by factoring.<br> 3z2 + 3z – 6 = 0<br> z = 3 or z = 2
lana66690 [7]

Answer:

<u>3</u><u>z</u><u>^2 + 3z - 6 </u>=0

3

3 (z^2 + z -2) = 0

3(z+2)(z - 1) = 0

z + 2-2 = 0 - 2

z = -2

z - 1 + 1 = 0 + 1

z = 1

Step-by-step explanation:

  1. factor out the GCF (3) and divide everything by it, and then set it equal to zero.
  2. since you have a degree of 2, factor it into two binomials that start with the square root of the first term and end with the square root of the second term.
  3. 3=0 is extraneous solution so we leave it, then we set each binomial equal to zero to solve for z.

note: your solutions is based on the degree or the exponent of the polynomial or the function.

Karen is typing a report.she typed 3/8of the pages in the report in the morning and 2/5 of the pages in the afternoon.what fract
Karolina [17]
Simple...

you have \frac{3}{8} and \frac{2}{5}

Just subtract...but first find a common denominator...

Use 40 as the common denominator...

\frac{3}{8} * \frac{5}{5} = \frac{15}{40}
and
\frac{2}{5} * \frac{8}{8} = \frac{16}{40}

So, subtract,

\frac{15}{40}&#10;-&#10; \frac{16}{40}

=- \frac{1}{40}

Thus, your answer.
