Answer:
Answer: D. 2(V[x} + V{x - 2}) Step-by-step explanation: As hinted in the question, we have to simplify the denominator. To understand it easier, let's imagine we have x - y in the denominator. If we multiply it with x + y we'll get x? - y, right? Check the next line: (x - y) (x + y) = x² + xy -xy - y? = x² - y? If we have the square of those nasty square roots, it will be much simpler to deal with. So, let's multiply the initial fraction using x+y, but with the real values: 4 x-2 x+Vx-2 x-2 4(Va+v-2) (V#)² -(væ–2)² Then we simplify: 4(va+væ-2) 4(Va+va-2) (Væ)2-(Va-2)2 2(Va + Va – 2) 4(va+va-2) (x) -(x-2) 2 Answer is D. 2(V{X} + v{x - 2})
Answer:
see explanation
Step-by-step explanation:
(18)
Since BD is an angle bisector , then
∠ DBC = ∠ ABD = 57°
∠ ABC = ∠ ABD + ∠ DBC = 57° + 57° = 114°
(19)
Since BD is an angle bisector , then ∠ ABD = ∠DBC
∠ ABC = 110° , so
∠ ABD = ∠ DBC = 110° ÷ 2 = 55°
Answer:
i dont think theres engouh info to answer that
Step-by-step explanation:
It's true
There is no repeating x values that have different y values
Answer:
151°
Step-by-step explanation:
Pentagons interior angles are always 540°. So to solve, you must put
540= (5x+2)+(10x-3)+(8x-19)+(7x-11)+(13x-31). After solving this you will get x=14 and you can now substitute x in for measure s.
13(14) -31
182 - 31
measure of s = 151°
