Answer:
18a(2bc + 3d)
Step-by-step explanation:
36abc + 54ad
Step 1: Find the Highest Common Factor of each
36abc = 2×2×3×3×a×b×c = 18a × 2bc
54ad = 2×3×3×3×a×d = 18a × 3d
HCF = 2×3×3×a = 18a
Step 2: Factor out with HCF
18a(2bc + 3d)
x=127 that is because a rectangle equals 365 degrees and two sides have to be parallel so 53+53=106 and 365-106=254 and 254/2=127
9.7 x 10^3
It is the same as 3600 + 6100 = 9700 => 9.7 X 10^3
