1/4 because there is 2 LR ads and 6 other ads, making a total of 8 and 2/8 simplifies to 1/4. Hope this helped!
Answer:
A. 6.75
Step-by-step explanation:
8x+18=4x+57
8x-4x=57-18
4x=39
4x+57=180-(8y+30)
39+57=180-8y-30
96=150-8y
8y=150-96
= 54
y= 54/8 = 6.75
Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The options are:
A) -x⁴ - 2x - x + 2
B) -x⁴ - 2x³ + 2x + 5
C) -2x³ + 1
D) -x - 2x² + 2x + 5
We have an expression:
= (x + 3) - [(x + 2)(x³ - 1)]



Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
