Answer: (x+2)^2 -1
x^2+4x+3=x^2+4x+3 (4)-(4)
Complete the square: -1+(x^2+4x+4) =-1+(x+2)^2
Answer: (x+2)^2 -1
Step-by-step explanation:
First you need to find the area of the lawn. To find the area of a square, you multiply two sides together. You have two sides given, which is super helpful.
I put in my calculator, (40+4/5)x(50+7/8) and this gave me the answer of 2075.7.
You need to then divide that number by 500, and divide it by 300, and then round up, cause if you round down you’re not gonna have enough seed.
2075.7/500 = 4.1514, but then this needs to be rounded up or he’ll be 0.1514 short. So he needs 5 bags for the highest setting.
2075.7/300 = 6.919, so for the lowest setting, he needs 7 bags of seed.
This should be correct.
Hope this helps :)

Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
