Distributive property
a(b+c)=ab+ac
also
(x^m)(x^n)=x^{m+n}
so

-8x^2(2y-3x)=-8x^2(2y)-8x^2(-3x)=
(-8)(x^2)(2)(y)+(-8)(x^2)(-3)(x^1)=-16x^2y+24x^3

Solve both! For x<br><br> |X + 2| &gt; 5<br><br><br><br> |X + 2| &lt; 5
NISA [10]

Answer:

Your Answer is ...

x > 3 or x < -7

Step-by-step explanation:

1.  x > 3 worked out

|X + 2| > 5

Solve absolute Value

|X + 2| > 5

We know either |X + 2| > 5 or x + 2 < - 5

_________________________________

x + 2 > 5\\x + 2 - 2 > 5 - 2 (Subtract ~2~ from~Both~sides)\\ x >3

2. x < -7 Worked out

x + 2 < - 5\\x+2-2>5-2 (Subtract~2~from~Both~sides)\\x

Hope this Helps!

Take Care!

MN is a diameter of a circle with centre ' O ' . If BD = CD , prove that ∠OAD = ∠OCD
Varvara68 [4.7K]

Answer:

\sf \: Proved \: \angle \: OAD  \:  =  \angle \: OCD

Step-by-step explanation:

<em>Given:</em>

Mn is diameter of circle having centre O

and BD = OD,

<em><u>To prove that:</u></em>

<u>\angle \: OAD  \:  =  \angle \: OCD</u>

<em>Solution:</em>

Join the points O and B and draw OB,

On joining the line,

in ∆OCD and ∆OBD,

OC =OB → (Radius of same circle)

BD =CD → (from given)

OD =OD → (Common side in both the triangles)

Hence ∆OCD and ∆OBD are congruent from SSS property.

so we can say that,

\angle \: OBD  \:  =  \angle \: OCD

Consider above prove as statement A

Corresponding angles of congruent traingle.

in ∆ OAB,

OA = OB (radius of same circle)

hence ∆OAB is an isosceles traingle.

We know that opposite angle of isosceles traingle are always equal. hence,

\angle \: OBD  \:  =  \angle \: OAB \\ \angle \: OAB  \:  =  \angle \: OAD (same \: angles) \\ \angle \: OBD  \:  =  \angle \: OAD

Consider above prove as statement B

From Statement A & B we can say that

\angle \: OAD  \:  =  \angle \: OCD

(HELP ASAP)
aleksley [76]

Answer: The true statement is,

'N is the mid point of JL'.

Step-by-step explanation:

Since, By the given diagram we get the following information,

M is mid point of KL because, KM=ML,

N is the mid point of JL Because, JN=NL

If we connect the points M and N then we get a line MN,

Which is called mid segment.

And, By the Mid point theorem,

MN\parallel KJ and MN= KJ/2 = 12.8/2=6.4 m

Therefore from the above information we can say that only second Option  is correct.
