3 + 5 . (-3)= 5 . ( - 6 + 2 ) - 4=
- 5 + 8 . 2 + 1=
4/6 + 13/6 - 5/6=
2 . 8 - 5 . (3 - 4)=
7/3 . 5/2=

Step-by-step explanation:

PEMDAS rule

3 -15 = -12

-20 - 4 = -24

-5 + 16 + 1 = 12

= 12/6 which = 2

15 + 5 = 20

35/6 = 5 5/6

FG = 28 meters

Step-by-step Explanation:

==>A design ABCD and its dilated photocopy EFGH.

Length of side AB = 17m

BC = 14m

DA:HE = 1:2

==>Required:

Length of side FG on the photocopy EFGH, in meters.

==>Solution:

Dilation of design ABCD would, upon transformation would produce a photocopy EFGH that is similar. Thus, ABCD ~ EFGH

Since ABCD is similar to EFGH, it means the ratio of their corresponding sides would be the same, and also have the same scale factor.

Therefore, it means DA:HE = BC:FG

Therefore, let's find length of side FG of the photocopy using the ratio1:2 that is given for DA:HE, which would also apply as the scale factor or ratio for all other corresponding sides.

Thus,

1:2 = BC:FG

1:2 = 14:FG

1/2 = 14/FG

Cross multiply to solve for FG

1×FG = 14×2

FG = 28 meters
