Answer:
KL = 6
Step-by-step explanation:
IJ + JK +KL = IL
9+ 11 + KL = 26
Combine like terms
20 + KL = 26
Subtract 20 from each side
20+KL -20 =26-20
KL = 6
Answer:
x = 6
Step-by-step explanation:
7 x = 56-14
7 x = 42
7 x/7 to remain with x only = 42
then x = 6
=(140+4) / 8
=(144/8) + (4/8)
=18 + 2

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,
