Answer:
5.4cm
Step-by-step explanation:
In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.
The ratio of their perimeter is
perimeterofΔ2 15
--------------------- = -------------
perimeterofΔ1 25
So, the side of triangle 2 will be
9 * 15 15
---------------- = --------------
sideofΔ2 25
=
⟹side of Δ2= 25 / 9∗15 =5.4.

Take 45.36 *.08 to get the price of the sweater 45.36 *.08 =3.6288 so take 45.36-3.63= 41.73 and take 41.73 *.25 = 10.4325 take 41.73+10.43=52.16 is the original price of the sweater
Answer:
Step-by-step explanation:
hg(x) means you multiply h(x) times g(x) and then we will set it equal to 
.
hg(x) = 
which simplifies to
. Now set that equal to :
and get everything on the same side and factor:
. Factor by grouping:
and factor out what's common in each set of ( ):
which factors out to
. But 
factors somoe to:
(x + 1)(x - 1)(x - 1) = 0 So the solutions for this are
x = -1, 1
