Lol hmmm. Never realized how hard distance formula was without knowing both starting x and y and end points aha
P= 12 + 4x^2 - 2 + x^2 + 3x^2
Combine like terms
12-2= 10
4x^2 + 3x^2 + x^2= 8x^2
P= 8x^2 + 10
Sorry if this isn't right but this is what I think you would do
The nonpermissible replacement of the variable in a certain expression is the value of x that will make the denominator of the expression zero. In this certain given,
6x + 3 ≠ 0
Solving for x,
x ≠ -1/2
Thus, the answer is -1/2.
Problem 23
A = 40
B = 3x+1
C = 3x+1
B and C are congruent, so they have the same angle measure
The three angles of any triangle add to 180 degrees
A+B+C = 180
40+(3x+1)+(3x+1) = 180
6x+42 = 180
6x = 180-42
6x = 138
x = 138/6
x = 23
Answer: B) 23

Problem 24
AB is the midsegment parallel to XY
So AB is half that of XY
AB = (1/2)*XY
AB = (1/2)*28
AB = 14
Answer: B) 14

Problem 25
Note the ratio of the given rectangle's sides: 7/12 = 0.583 roughly
Divide the answer choices in a similar fashion
A) 5/7 = 0.714
B) 14/36 = 0.389
C) 21/36 = 0.583
D) 21/48 = 0.4375
We get the same result in choice C as we did in the original rectangle
Answer: C) 21 ft x 36 ft
