Answer: $2d^2-2d$

Step-by-step explanation:

Given

$\Rightarrow (d^2-d+5)-(-d^2+d+5)\\\Rightarrow (d^2+d^2)-d-d+5-5=0-2d+0\\\Rightarrow 2d^2-2d=2d(d-1)$

$(2\sqrt{5}-\sqrt{2} )^2=(2\sqrt{5})^2-2*2\sqrt{5}*\sqrt{2} +(\sqrt{2})^2 } =4*5-4*\sqrt{2*5} +2=\\=20-4\sqrt{10}+2=22-4\sqrt{10}.$

Answer: E. None of these.

Question 47.

$\frac{4\sqrt{5} }{\sqrt{3} } =\frac{4*\sqrt{5}*\sqrt{3} }{\sqrt{3} *\sqrt{3} } =\frac{4*\sqrt{5*3} }{3}=\frac{4\sqrt{15} }{3} .$

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.

vampirchik [111]

Answer:

the "negative solution" is -3

Step-by-step explanation:

Represent the number by n.

Then n^2 - 24 = 5n

We rewrite this in standard quadratic form:

n^2 - 5n - 24 = 0

This factors as follows; (n + 3)(n - 8) = 0

The roots are n = -3 and n = 8. Thus, the "negative solution" is -3

James hiked on two trails. The first trail was l 2/5 miles long, and the second trail was 5 times as long as the first trail. Ho

Licemer1 [7]

Answer:

$6 \frac{2}{5} \: miles$

Step-by-step explanation:

$First \: trail = 1 \frac{2}{5} = \frac{7}{5} \: miles \\ \\ second \: trail = 5 \times first \: trail \\ \\ = 5 \times \frac{7}{5} \\ \\ = 7 \: miles \\ \\ total \: length = \frac{7}{5} + 5 \\ \\ = \frac{7 + 25}{5} \\ \\ = \frac{32}{5} \\ \\ = 6 \frac{2}{5} \: miles$
