Answer:
l=11
b=8
Step-by-step explanation:
Let l=x+3
b=x
Perimeter=38
i.e 2l+2b=38
2(l+b)=38
2(x+3+x)=38
2(2x+3)=38
4x+6=38
4x=38-6
x=32/4
x=8
-2/3, -0.3, 1/4, 0.75, 0.8
For this case:
D.-) The system has infinitely many solutions.
<h2>
Explanation:</h2>
Remember that you have to write complete questions in order to find exact and good answers. In this exercise, the system is missing. However, I'll provide the following system:
So we have two equations and two variables. Our first equation is:
And the second equation is:
When graphing these two lines, we can get the following possibilities:
- They have a unique solution. This means the graphs intersect at a single point.
- They have infinitely many solutions. This implies the lines are basically the same.
- They have no solution. This implies they are parallel but with different y-intersect.
By dividing equation (2) by 2 we get:
So we get the same equation as line (1), so <em>the conclusion is that they have infinitely many solutions.</em>
