How do you do 56 through 58? Thanks to anyone who awnsers!
astraxan [27]

Hello !

56)

5 {x}^{2}  + 8x =  - 1 \\ 5 {x}^{2}  + 8x + 1 = 0

\Delta =  {b}^{2}  - 4ac \\  =  {8}^{2}  - 4 \times 5 \times 1 \\  = 64 - 20 \\  = 44

The value of the discriminant is 44.

57) ∆>0 : there are two solutions.

58)

x_1 =  \frac{ - b +  \sqrt{\Delta} }{2a}  \\  =   \frac{ - 8 +  \sqrt{44} }{2  \times 5}  \\  =  \frac{ \sqrt{11} - 4 }{5}

x_2 =  \frac{ - b - \sqrt{\Delta} }{2a} \\  =  \frac{ - 8 -  \sqrt{44} }{2 \times 5}   \\  =  \frac{ -  \sqrt{11} - 4 }{5}

Have a nice day

Mary and Benjamin are driving to their friend Paar's house for a berday party Mary drives 9
SpyIntel [72]

Answer:

3.2 miles

Step-by-step explanation:

Given that Mary drives 9 miles north and 6 miles east to get there, the resultant miles will be achieved by using pythagorean theorem

R = sqrt ( 9^2 + 6^2 )

R = sqrt ( 81 + 36 )

R = sqrt ( 117 )

R = 10.82 miles

while Ben drives 3 miles south and 7 miles west

Use the same pythagorean theorem to find the resultant displacement

R = sqrt ( 3^2 + 7^2 )

R = sqrt ( 9 + 49 )

R = sqrt ( 58 )

R = 7.62 miles

The difference in miles to where Mary and Benjamin live will be difference in the resultant displacement of the two

Difference = 10.82 - 7.62 = 3.2 miles.

Therefore, Mary live 3.2 miles from Benjamin.

Can someone please help me?!!!
Natasha2012 [34]
SOLUTION:

Alternate angles on paralell lines.

This means:

2x + 10° = 62°

2x = 62 - 10

2x = 52

x = 52 / 2

x = 26


Sorry, I tried to answer this but I only got this far. I'm not exactly sure about the ? < x < ? as my answer didn't give an answer with > or <. Unless there are different numbers which you can put for your answer based on what ( x ) is equal to, I'm not sure what the answer is & I doubt that they would allow for multiple answers.
