Lisa's drawing has the following dimensions:
Width=43.5 cm
Length=934 mm
but 1 cm =10 mm
thus
934mm when converted into cm we shall have:
length=93.4 cm
To get the total length of material required to frame the picture, we calculate the perimeter.
P=2(L+W)
P=2(93.4+43.5) cm
P=2(136.9)
P=273.8 cm
The total length of material required will be 273.8 cm
Answer:

Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal.
To determine the scale factor calculate the ratio of corresponding sides, that is
=
= 
Answer:
x=24
Step-by-step explanation:
Answer:
A. 
Step-by-step explanation:
We need to determine whether the polynomial
can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.









Hence choice A.
is correct.
