Hi !!

Find the value of x :

We have :

• x + 2

• 3x - 6

Match the values to find x :

x + 2 = 3x - 6

x - 3x = -6 - 2

-2x = -8

x = 8/2

x = 4

* 4 + 2 = 3(4) - 6

6 = 12 - 6

6 = 6

Equality is checked, it is an isosceles triangle

Both the correct value is 4.

Factor. Explain. 24x³y²-4x²y+84x^4

Elan Coil [88]

Answer:

$\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}$

Step By Step Explanation:

Apply Exponent Rule $\bold{\:a^{b+c}=a^ba^c}$

$\bold{x^4=x^2x^2,\:x^3y^2=x^2x}$

$\bold{24x^2x-4x^2y+84x^2x^2}$

Rewrite 84: $\bold{21\cdot \:4}$

Rewrite 24: $\bold{6\cdot \:4}$

$\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}$

Factor Out Common Term $\bold{4x^2}$

$\bold{4x^2\left(6xy^2-y+21x^2\right)}$

➤ $\boxed{\bold{Mordancy}}$

Answer:

315

Step-by-step explanation:

1. This is not a scale rectangle and it angers me.

2. All you have to do is draw proportions.

5x7=35

15x21=315

Youll notice that 5x3=15 and 7x3=21 so it’s just proportions!

Help me help me answer this

Leya [2.2K]

If both triangles are congruent (that's what the sign means), then AD=CB, and CD=AB. Substituting what we are given into CD=AB,

6x-5=3x+10

Solving the equation:

3x=15

x=5

So we know that 2x+4 (the value of AD) becomes 2*5 +4, and you get 14. Since we know that AD=CB, then CB is also 14. No need to find y!

Answer: CB=14
