45.35 is your answer once you round it
B.32 You get this because a square is perfect, which means it's equal on all sides. So 8x4=32
First:
2x + 2z = 4
2(x+z)=4
x+z=4/2
x=2-z
-x - y - z= -8
-(2-z)-y-z= -8 replace x
-2+z-y-z= -8 (cancel z)
-2-y= -8
6 = y
Then:
-4x + 4y + 5z = 7 replace x and y
-4(2-z)+4*6 + 5z = 7
-8 + 4z + 24 + 5z = 7
16 + 9z = 7
9z = 7 - 16
9z = -9
z = -9/9
z= -1
Finally
x= 2-z replace z
x = 2- (-1)
x = 3
Answer:
12.04m = l
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
12^2 + 1 ^2 = l^2
144 + 1 = l^2
145 = l^2
Take the square root of each side
sqrt(145) = sqrt(l^2)
12.04159458 = l
To the nearest hundredth
12.04m = l
