a) 1 bag is $2.99
b) 9 bags are $26.91.
$11.96/4 is 2.99
So one bag costs $2.99 and for any rest of number of bags we just multiply that number by 2.99!!
Hope this helps. :)
Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.
-- Remember this only works on perfect square polynomials.
Clear the fraction <span>When equations have a lot of fractions in them, the easiest way to solve them is to first clear all the fractions. In order to do this, </span>you must multiply every term by the LCD (least common denominator).<span> </span>
B.) 30 miles
You needed to add all the numbers together then divide by the amount of numbers there which is 4. (ex: 36 + 26 + 30 + 28 = 120 120<span>÷4= 30)
hope that helps!</span>
Answer:
3n
Step-by-step explanation:
When subtracting like terms (numbers, or variable expressions that have the same variable, like these), you add the coefficients (the numbers attached to the variable) to simplify the expression.
5n - 2n
You have 5 "n"s and you subtract 2 "n"s, leaving you with 3 "n"s
