Answer:

Step-by-step explanation:

L = 3*w + 1 Given

P = 2*(L + w) Formula for Perimeter. Substitute for L

P = 2*(3w + 1 + w) Combine

P = 2*(4w + 1)

P = 58 Given

58 = 8w + 2 Remove the brackets

58 - 2 = 8w Subtract 2

56 = 8*w Divide by 8

56/8 = w

7 = w

================

Find L

L = 3*w + 1

L = 3*7 + 1

L = 22

================

Check

2L + 2W = 58

2*22 + 2*7 =? 58

44 + 14 = ? 58

58 = 58

The answer checks.

_____ + 5 3/4 = 9 5/8<br>please help you will get 75 points

Answer:

3 7/8

Step-by-step explanation:

_____ + 5 3/4 = 9 5/8

x + 5 3/4 = 9 5/8

Subtract 5 3/4 from each side

x + 5 3/4 - 5 3/4 = 9 5/8 - 5 3/4

x = 9 5/8 - 5 3/4

Get a common denominator of 8

5 3/4 *2/2 = 5 6/8

x = 9 5/8 - 5 6/8

We need to borrow 1 from the 9 in the form of 8/8

x= 8 + 8/8+ 5/8 - 5 6/8

x = 8 13/8 - 5 6/8

= 3 7/8

Solve for x in the equation x²-12x+59=0

lyudmila [28]

${x}^{2} - 12x + 59 = 0 \\ {x}^{2} - 12x + 36 + 23 = 0 \\ {x}^{2} - 12x + 36 = - 23 \\ {(x - 6)}^{2} = - 23 \\ x - 6 = + - \sqrt{ - 23} = + - i \sqrt{23} \\ x = 6 + - i \sqrt{23}$

mean

$x = 6 + i \sqrt{23}$

$x = 6 - i \sqrt{23}$
