We know that the area of a rectangle is equal to the width multiplied by the length. So in this case the algebraic expression is (x+5)*(3x+10). You get 3x^2 +10x +15x +50= 3x^2 +25x +50.
Answer:
<h2>2. Because 25<12, this equation can not be true.</h2>
Step-by-step explanation:
I just solved the equation and 1/2 + 3/8 = 7/8 or 87.5%.
4/10 equals 40%.
Since these two do not sync up, the equation must be false and 2 is the only answer saying the equation is false.
I'm always happy to help :)
The function of f(x)=-x+4x-3 is 3x-3. I hope this helps. :)
To find slope, we must find the change in y values divided by the change in x values, also called the rise/run. This is modeled below:
Slope = m = (y1 - y2)/(x1-x2) = (6-(-3))/(1 - (-6)) = (6+3)/(1+6) = 9/7
We can check that this answer is correct by consulting the graph. The graph shows a positive correlation (means that the slope should be positive), and if you count the graph unit squares, you get that the graph moves up 9 squares and over 7 squares between the two points shown, letting us know we got the right answer.
Hope this helps!
