Step-by-step explanation:
2x (5x - 1) + (3x^2 - 7x - 2)
= 10x^2 - 2x + 3x^2 - 7x - 2
= 13x^2 - 9x - 2
a = 13
b = -9
c = 2
Answer:
-45
Step-by-step explanation:
The question is asking for the sum of the sequence. Therefore, there is no such thing as a "radians" answer.
When you evaluate the sum, you should get -45 as your answer. To find so, you simply plug in 1 as <em>n</em> and other numbers then add the result.
To find the average you add up all the trials (13 + 9 + 7) divided by the amounted trials (3)which equals 9.67s
14+17+11/3 = 14
16+ 21 + 19/3 = 18.67
Answer:
intersection is what point satisfies both equaitons
divide second equation by 2 for simplificy
2x-y=8
oh dear, we got the same equation
therefor they are the same line
infinitely many points
anywhere on the line 2x-y=8
some points are
(4,0)
(5,2)
x2 − 10x − 24 x 2 - 10 x - 24 this expression is equivalent to x² 10x 24 (x 1)(x 24) (x 4)(x 6)(x 2)(x 12)(x 3)(x 8).
<h3>What are algebraic expressions?</h3>
A logarithmic articulation is a numerical expression that incorporates factors, constants, coefficients, and mathematical tasks. To increase two logarithmic articulations, we duplicate each term of the main articulation with each term of the subsequent articulation and join every one of the items. In a mathematical articulation, a term might comprise of a steady, one variable, a result of at least two factors, a result of both the variable and consistent part. Moreover, the mathematical terms can be both positive and negative. There are significantly three sorts of mathematical articulations.
