Can someone help me with this question please

here

a) 3-9h= 3(1-3h)

b) 18h^2-6h= 6h(3h-1)

c) 12h+21h^2= 3h(4+7h)

d) 6h^2-2h=2h(3h-1)

here greatest factor among all is 6h

so answer is 18h^2-6h

hope it helps

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
