The answer is 1/2
step by step: 1×1=1 so then you can do 5×4 which is 20 so that is 1/20
The correct answer is 1.7 times 10^3.
See diagram
totalarea=totallengtht times totalwidth=(2a+5) times (2a+7)=4a²+24a+35
minus original aera
which is 5 by 7 which is 35
4a²+24a+35-35=4a²+24a
3rd option I think, can't tell which is which
The compound inequality for real numbers between -8 and 3 is -8
