ns +sb = 5.4 cm
sb = en so en can be plugged in for sb
therefor es = 5.4
Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60
Okay so you know a straight line is equal to 180 degrees, so you set them up in an algebraic equation. (5x+2)+48=180 subtract 48 first to get 5x+2=132 Subtract the 2 this time to get 130. Now you end up with 5x=130. Here you divide 130 by 5 to get X=26. If you just need to find the degree of that angle tho you can stop after the first subtraction because the math tells you (5x+2)=132 degrees.
Answer:
2x+8 and 2(4+x)
Step-by-step explanation:
Its 2x+8 because all you have to do is distribute the 2. So 2 times x is 2x and 2 times 4 is 8. You can just rearrange it for 2(4+x)
