Answer: 32
Step-by-step explanation:
A square is the same length on each side so each side would be 9
9+9+9+9= 36ft (perimeter)
Again each side if 9 feet to find the area u just multiply the length and width here the length and width are the same (9)
9•9= 81 (area)
The answer is the first option, <-20, -42>.
We can find this by first finding what -2u would equal by multiplying <5, 6> by -2. This gives us <-10, -12>.
Then we need to find out what 5v is equal to, by multiplying <-2, -6> by 5 to get <-10, -30>.
Now that we know what -2u and 5v are, we can substitute them into the equation and get
<-10, -12> + <-10, -30>, which we can split up into -10 - 10 = -20, and -12 - 30 = -42, so your final answer is <-20, -42>.
I hope this helps!
