Answer:

True.

If Δ ABC ≅ Δ DBC then BC bisects the angle ∠ ACD.

Step-by-step explanation:

Δ ABC ≅ Δ DBC

∠ ACB ≅ ∠ DCB {corresponding angles of congruent triangles}or(c.p.c.t)

i.e BC is the bisector of ∠ ACD

Hence, TRUE

What is the solution set of x2 + 5x + 1 = 0?

DerKrebs [107]

Answer:

$\huge\boxed{\left\{-\dfrac{5+\sqrt{21}}{2};\ \dfrac{-5+\sqrt{21}}{2}\right\}}$

Step-by-step explanation:

$x^2+5x+1=0\\\\\text{Use the quadratic formula:}\\\\\text{For}\ ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\\text{if}\ \Delta < 0,\ \text{then the equation has no real solution}\\\text{if}\ \Delta=0,\ \text{then the equation has one real solution}\ x=\dfrac{-b}{2a}\\\text{if}\ \Delta>0,\ \text{then the equation has two real solution}\ x=\dfrac{-b\pm\sqrt{\Delta}}{2a}$

$\text{We have}\\\\a=1,\ b=5,\ c=1\\\\\Delta=5^2-4(1)(1)=25-4=21>0\\\\x=\dfrac{-5\pm\sqrt{21}}{2(1)}=\dfrac{-5\pm\sqrt{21}}{2}$

Amia has $300 to plan a trip with her cousins. She wants to go to Orlando, Florida and it costs $127 for a room, $75 for gas rou

zhuklara [117]

First let's add the room cost and the gas.

127+75= 202

Let's subtract that from 300.

300-202= 98

Divide 98 by 20.

20 can only go into 98 4 times.

Amia can only bring 3 cousins, since one of those 4 tickets are for her.

I hope this helped you.

Brainliest answer is always appreciated.
