No because from what I understand,
2w + 2l = p so
2(20) + 2(11) = 64 if that was true, both sides would be equal.
40+22+=64
62=64 and they are not.
Remark
When you have two parallel lines cutting the sides of a triangle and one of them is the base of the triangle, then the 2 sides cut form a proportion. The safest way to handle this is to set up the proportion so that you are talking about sides of similar triangles..

BD || AE
CD = 16
CE = 16 + 4
CB = 12
CA = 12 + x
Set Up the Proportion
CD/CE = CB / CA
Substitute and Solve
16/20 = 12/(12 + x) Cross multiply
16*(12 + x) = 20 * 12 Combine the right
16*(12 + x) = 240 Remove the brackets.
192 + 16x = 240 Subtract 192 from both sides.
16x = 240 - 192
16x = 48 Divide by 16
x = 48 / 16
x = 3
Depends which prism
Rectangular prism volume is LWH
Answer:
Step-by-step explanation:
Divide everything by 2
Divide everything by -1 and since y is negative, you flip the sign
Answer:
Step-by-step explanation:
The trick to this is looking at the denominator. If the numerators are the same for all fractions you are comparing then things are going to be a bit easier for comparing them. The one that has the biggest denominator is small and the one with the smaller denominator is a bigger fraction.
hope this makes sense
