Answer:
87
Step-by-step explanation:
common difference = d = 2
an = a1 + (n-1)*d
a43 = 3 + 42*2 = 87
Answer: d = ±10
<u>Step-by-step explanation:</u>
169 = 
+ 
169 = (12)² + 
169 = 144 +
25 =
100 = d²
√100 = √d²
±10 = d
You cannot solve this, I don’t see how....

Answer:
Width =15
Length =33
Step-by-step explanation:
Take width as x
And length as 2x+3
Perimeter as 96
Formula of the perimeter of a rectangle is 2l+2w
X+×+2×+3+2×+3=96
6x+6=96
6x=96-6
6×=90
X=15
Width =x and x =15 so width =15 while length =33
