Answer:
A) x=46
Step-by-step explanation:
The triangles are congruent, which means the angles are congruent as well. Therefore, we can set angles ADC and ABC equal to each other to solve for x:
100=2x+8
92=2x
46=x
Therefore, A is correct
Answer:
C)10.2
Step-by-step explanation:
A is not the correct answer because it is way less than 10.2 and 10.3.
B is not correct because although it has 10, the numbers behind the points are in the ten thousandths place, being less than 10.2.
Then, D is incorrect because it is bigger than the range between 10.2 and 10.3
<em><u>Leaving C with your correct answer</u></em>
Answer:
x ≤ a → x ∈ (-∞, a]
x < a → x ∈ (-∞, a)
x ≥ a → x ∈ [a, ∞)
x < a → x ∈ (a, ∞)
--------------------------------------
Therefore:
x ≥ 7.8 → [7.8, ∞)
x < 7.8 → (-∞, 7.8)
x ≤ 7.8 → (-∞, 7.8]
x > 7.8 → (7.8, ∞)

Step-by-step explanation:
Answer:
-12r² + 10xr - 15x + 34r - 24
Step-by-step explanation:
1. Organize it, variables first - as well as adding constants such as 4 and -7
(5x - 6r + 8) (2r - 3)
2. Start by multiplying the 5x by (2r - 3), then -6r, followed by 8
(10xr - 15x) + (-12r^2 + 18r) + (16r - 24)
3. Simplify
10xr - 15x - 12r² + 18r + 16r - 24
4. Order by greatest to smallest factorial
-12r² + 10xr - 15x + 18r + 16r - 24
5. Combine like variables
-12r² + 10xr - 15x + 34r - 24
The answer will be $29.9K
