Answer:
Length of longer length=132 inches
Length of shorter length=33 inches
Step-by-step explanation:
Step 1: Determine total length of pipe
Total length of pipe=165 inches
Step 2: Derive expression for all the lengths
We can express all these lengths as follows;
L=l1+l2
where;
L=total length
l1=length of longer piece
l2=length of shorter piece
but;
length of longer piece=4×length of shorter piece
replacing;
l1=4l2
replacing;
L=165
l1=4×l2
165=l 2+4 l2
5 l2=165
l2=165/5
l2=33 inches
l1=length of longer length=33×4=132 inches
l2=length of shorter length=33 inches
The surface area will increase by a factor of 49/16
Answer:
The answer is 95cm2
Step-by-step explanation:
A=b×h
=19×5
= 95 cm2
please mark me the brainliest
The ANSWERRRRRRR would be 32
The answer is 50 because if u add 20 and 50 it makes 70:)
