Answer:
It is a
IStep-by-step explanation:
First off you have to have the quadrtic formula to the nine power then you multiply it by 5 then subtract two
The given algebraic expressions 5xy and -8xy are like terms because of the similarity in their variable and it's power.
As per the question statement, we are given algebraic expressions 5xy and -8xy and we are supposed to tell whether these two terms are like or not.
We know that in Algebra, the phrases or terms that include the same variable and are raised to the same power are referred to as "like terms."
Hence as the variable part in the expressions, 5xy and -8xy, are same hence they can be added and subtracted hence are called like terms.
- Algebraic expressions: An expression which is constructed using integer constants, variables, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)
- Like terms: The definition of similar words is the terms that have the same variable raised to the same power. Only the numerical coefficients can alter in terms that are similar to algebra. We may combine similar words to make algebraic expressions simpler, making it much simpler to determine the expression's outcome.

Answer:
357 passengers
Step-by-step explanation:
(The 
is 85% of the 100% people because 15% is missing)
When you cross-simplify you get: 
which is 
Finally, multiply 17 by 21 to get x.
Therefore, x=357
Answer:
A) Measure of an interior angle of polygon = 150°
B) No of sides = 12
C) Sum of all interior angles = 1800°
Step-by-step explanation:
Measure of interior angle of polygon = 180°- measure of exterior angle of polygon
= 180°-30°
= 150°
B.
Answer:
2%
Step-by-step explanation:
You can convert percents into decimals by moving the decimal point(the period) two steps to the left. For example 2% goes to .02 in decimal form. Once you do that then you can multiply by the length the metal pipe was supposed to be and you get .6, since the piece of metal ended up being .6 centimeter off, the answer is 2%. sorry if it's not a good explanation ;-;.
