For finding, the sum of last ten terms, we write the given AP in reverse order i.e, 126, 124, 122,..., 12, 10, 8
Hence,first term (a) = 126, common difference, (d) = 124 - 126
So,
Answer:
x=26
Step-by-step explanation:
since the equation is vertical to 155 the equation would be
5x + 25 = 155 and then you would solve for x like this
1).<span>12.2302158 or $12
</span>85/6.95=<span>12.2302158</span>
2). 3.7 miles per day
11.1/3=3.7
Technically, all of the choices can be written as a difference of squares. Just find the square root of both terms and use the formula
where and are terms.
However, I am going to assume that your problems want to know if the expressions can be written as a difference of two squares, where and are either variables with an even exponent or a perfect square, as this is what many instructors are asking for.
A) A cannot be written as a difference of two squares, because even though 25 is a square, is not a variable with an even exponent, which means that we can not apply the Differences of Squares.
B) Similar to Choice A, we cannot apply the Differences of Squares given the context because 18 is not a perfect square.
C) We can apply it to Choice C, since has an even exponent and 36 is a perfect square. Applying the formula, we get:
If in standard form you mean slope intercept form, then you are looking to create an equation that looks like this:
y = mx + b
So you need to move around the numbers whilst keeping both sides equivalent.
3x - 9 = 7y
7y = 3x - 9
y = (3x)/7 - 9/7
Your answer should look like this:
y = (3x)/7 - 9/7
If this is not what you meant by standard form please comment and I will see if I can adjust the answer.
