Answer:
the Expression is :
(3) × (1 + 6d + 7y)
Step-by-step explanation:
here's the solution : -
=》
=》
now, since 3 is common in all terms let's take it out.
=》
=》so, ,we got the above expression as product of 3 and ( 1 + 6d + 7y ) as factors.
Estimate the product by rounding each number to its greatest place value of 2342.7 times 784.3

Answer:
D'G' = 52.5 units
Step-by-step explanation:
Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5
D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )
G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )
Calculate D'G' using the distance formula
d =
with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)
D'G' =
=
=
=
= 52.5 units
