Step-by-step explanation:
Answer:
First Picture: Length = 30.82in
Second Picture: Length = 34.64in
Step-by-step explanation:
Given
Picture 1:
Area = 950in²
Picture 2:
Area = 1200in²
Required
Determine the length of each pictures
From the question, we understand that both pictures are square in shape and the area is calculated as thus:
Area = Length²
For the first picture, substitute 950 for Area
This gives:
950 = Length²
Length ² = 950
Take square root of both sides
Length = √950
Length = 30.8220700148448822
Length = 30.82 (approximated)
Hence, the length of the first picture is 30.82in
For the second picture, substitute 1200 for Area
This gives:
1200 = Length²
Length² = 1200
Take square root of both sides
Length = √1200
Length = 34.6410161513775458
Length = 34.64 (approximated)
Hence, the length of the second picture is 34.64in
Simply going to factorise this:
v(v - 1) -2(1 - v):
Note 1 - v = -(v-1)
<span>v(v - 1) -2(1 - v)
</span>
<span>v(v - 1) -2(-(v - 1))
</span>
<span>v(v - 1) +2(v - 1)</span>
(v + 2)(v - 1)
