Question

Its about geometry i need help its urgent

Answer 1

see below

Explanation:

22 15

1. L -----------------M------------N LN = 22 + 15 LN = 37

31 ??

2. L -----------------M------------N MN = 54 - 31 MN = 23

|<-----------54 ---------------->|

6X+1 X+7

3. R -----------------S------------T find X

(6x + 1) + (x + 7) = 0

7x = -8

x = - 8/7

47 3X+10

4. D -----------E---------------------F find EF

|<--------- 9X - 39 ------------>|

47 + (3x + 10) = (9x - 39)

3x - 9x = -39 - 10 -47

-6x = -96

x = -96 / -6

x = 16

EF = 3x + 10

EF = 3(16) + 10

EF = 58

Answer 2

1) 37

2) 23

3) x = 4

4) 58

Explanation:

1) 15 + 22 = 37

2) 54 - 31 = 23

3) 6x + 1 + x + 7 = 36

7x + 8 = 36

7x = 28

x = 4

4) 3x + 10 + 47 = 9x - 39

57 = 6x -39

96 = 6x

16 = x

3(16) + 10 = 58
