The one that does not belong is plane CDE, the reason being the rest are line segments. Line segments differ from the planes because they have fewer number of dimensions as compared to the planes. Thus the correct answer is:
plane CDE
reason being:
The one that does not belong has different number of dimensions
Answer:
The values of x = y = z = 1
Step-by-step explanation:
Given three linear equation as ,
x + 2y + z = 4 .......a
4y - 3z = 1 .......b
y + 5z = 6 ........c
Now solve eq a and b first
4y - 3z = 1 × 5
y + 5z = 6 × 3
Or, 20y - 15z = 5
3 y + 15z = 18
so ,(20y - 15) + (3y +15 ) = 5 +18
or, 23 y = 23
∴ y = 1
Now put this y value in eq c
so , 1 + 5z = 6 ,
Or, 5z = 6-1 =5
∴ z = 1
Again put this y and z value in eq a
so, x + 2(1) + (1) = 4
Or, x = 4 -3
∴ x = 1
Hence from the above solutions , the value of x = y =z = 1 Answer
16 / x = -8
First, let's divide both sides by x.
16 = -8x
Divide both sides by -8
-2 = x
16 / -2 = -8
Angle c and angle d are congruent. Congruent means they have the same the measure, or they have EQUAL measures. You set the two values equal to each other and solve for x.
X+26=2x-10 subtract x from both sides
26=x-10 add 10 to both sides
36=x
Now substitute x back in for angle d.
2(36)-10 = 62
Area equals three time the square root of three all of this divided by 2 times the length of the side squared. So this would be 1039.23mi^2
