Answer:

D. 7

Step-by-step explanation:

(8+4) = 2(x-1) multiply (x-1) by 2

(8+4) = 2x-2 add 8 and 4

12 = 2x-2 add 2 on both sides

14 = 2x divide both sides by 2

7 = x

kap26 [50]

Answer:

The answer is

<h2>1225</h2>

Step-by-step explanation:

4x² + 5 - 6x³ + 3x⁴ - x

x = - 4

Substitute the value of x into the expression

That's

4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4

Simplify

4(16) + 5 - 6( -64) + 3( 256) + 4

64 + 5 + 384 + 768 + 4

We have the final answer as

<h3>1225</h3>

Hope this helps you

How can you classify the results of operations on real numbers? <br>​
choli [55]
Closure property: If a and b are real numbers, a+b is also a real number.
- Associative property: a+(b+c) = (a+b)+c.
- Commutative property: a+b = b+a.
- Additive identity: a+0 = a.
- Additive inverse: a + (-a) = 0.
