Answer:

Step-by-step explanation:
A polynomial written in decreasing order of the degree of its monomials ( or single term ) is called its standard form,
In polynomial,
,
Degrees are written in increasing order,
⇒ It is not written in standard form,

Answer: C
Step-by-step explanation: simply apply the distributive property to each half of the expression to be left with terms that can be combined.
(8x + 16y)/2 = 4x + 8y
4(x - y) = 4x - 4y
(4x + 8y) + (4x - 4y) = 4x + 4x + 8y - 4y
= 8x + 4y => C
Answer: B
Step-by-step explanation:
Answer:
16 x¹⁰ + 88 x⁵ + 121
step-by-step explanation:-
( 4 x⁵ + 11)²
- use ( a + b)² = a² + 2ab + b² to expand the expression
( 4x ⁵)² +2 ( 4x⁵) ( 11 ) + ( 11 )²
calculate we get
16 x¹⁰ + 88 x⁵ + 121
Answer: 9/7 or 1.3 (rounded)
reasoning: -2 + 7x/9 = -1
7x/9 = 1
7x = 9
x = 9/7, or 1.3 (assuming they allow you to round to the nearest tenth)
