2/a=(2.5/1.25), 2=2/a, a=1
Answer:
7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.
On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.
For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.
Answer:
3√2
Step-by-step explanation:
this is called 45° ~ 45°~ 90° special triangle
the right angles has a length of x while hypotenuse has x√2
since in this triangle the given right sides' length = 3, hypotenuse must be = 3√2
You must use the t-distribution table when working problems when the population standard deviation (σ) is not known and the sample size is small (n<30). General Correct Rule: If σ is not known, then using t-distribution is correct. If σ is known, then using the normal distribution is correct.
