75/25= 3
72/24= 3
7*3= 21
x= 21
I hope this helps!

Answer:
n(a) X n( b) = 6
Step-by-step explanation:
n(a)= 2
n(b) = 3
n(a) X n( b) = 2x3
=6,,
Y-intercept is of the graph is 0
Yes both equations are equal because when you do distributive property it is the same
In a nutshell, the Riemann's sum that represents the <em>linear</em> equation is A ≈ [[4 - (- 6)] / 5] · ∑ 2 [- 6 + i · [[4 - (- 6)] / 5]] - [[4 - (- 6)] / 5], for i ∈ {1, 2, 3, 4, 5}, whose picture is located in the lower left corner of the image.
<h3>How to determine the approximate area of a definite integral by Riemann's sum with right endpoints</h3>
Riemann's sums represent the sum of a <em>finite</em> number of rectangles of <em>same</em> width and with <em>excess</em> area for y > 0 and <em>truncated</em> area for y < 0, both generated with respect to the <em>"horizontal"</em> axis (x-axis). This form of Riemann's sum is described by the following expression:
A ≈ [(b - a) / n] · ∑ f[a + i · [(b - a) / n]], for i ∈ {1, 2, 3, ..., n}
Where:
- a - Lower limit
- b - Upper limit
- n - Number of rectangle of equal width.
- i - Index of the i-th rectangle.
Then, the equation that represents the <em>approximate</em> area of the curve is: (f(x) = 2 · x - 1, a = - 6, b = 4, n = 5)
A ≈ [[4 - (- 6)] / 5] · ∑ 2 [- 6 + i · [[4 - (- 6)] / 5]] - [[4 - (- 6)] / 5], for i ∈ {1, 2, 3, 4, 5}
