Dilation is either : enlargement or shirking.
Simply you multiply the ordered pair times the dilation vector (Origin-Centered)
D.F = dilation factor;
d.f = 5
C' = d.fC
when you multiply a constant times an ordered pair , it multiples into each of the pair.
C' = 5 ( -5 , 1 ) = ( -25, 5 )
In case you were asked for A' , B' (test yourself before checking)
A' = 5 (-4,3) = ( -20 , 15)
B' = 5 ( 2, 3 ) = ( 10, 15)
Dividing the dilated by the original pair results in the dilation factor
A'/A = (-20/15)/(-4,3) = 5(-4,3)/(-4,3) = 5
Step-by-step explanation:
7 (x+12) - 4
7x + 48 -4
7x + 44
Step-by-step explanation:
1 ) 402
402 - 2 = 400 which is a perfect sqrt ( 20)^2
so u must subtract 2
2) 1989
1989 - 53 = 1936 which is a perfect sqrt (44)^2
3) 3250
3250 -1 = 3249 which is a prefect sqrt (57)^2
4) 4000
4000 - 31 = 3969 which is a perfect sqrt (63)^2
Answer:
(8h+3) x (2h-3)
Step-by-step explanation:
Rewrite the expression, write -18 as a difference: 16h^2+6h-24h-9
Factor out 2h from the expression: 2h x (8h+3)-24h-9
Factor out -3 from the expression: 2h x (8h+3)-3(8h+3)
Factor out 8h+3 from the expression: (8h+3)x(2h-3)
Hope this helps! If you have any questions pls ask. Have a very wonderful day!!
