-6.4 – 4(-2.8)
-6.4 – - 11.2 = 4.8
Your answer is B: 4.8
Answer:
x= -11.9
Step-by-step explanation:
-8 - 3.9 = -11.9
-11.9+ 3.9 = -8
The area of a square is simply the side length squared and we are given that the area is 125 so:
s^2=125
s=√125
s=5√5
Now using the area equation again, and adding 1 inch to s we have:
A=(s+1)^2, and using s found above we have:
A=(5√5+1)^2
A=125+10√5+1
A=126+10√5 in^2
A≈148.36 in^2 (to nearest hundredth of a square inch)
3x3 -4= 5 5(-1)= -5 -5(-4)= 20
