Answer:
Length = 13 cm
Width = 10 cm
Step-by-step explanation:
We are told that;
- The length of the rectangle is 3 cm more than the width
- Thus taking, the width as x cm
- Then, the length will be (x+3) cm
- The perimeter of the rectangle is 46 cm
We are required to determine the dimensions of the rectangle;
We know that the perimeter of a rectangle is given by the formula;
P = 2(l+w)
In this case;
46 = 2 ( x + x + 3)
Thus;
4x + 6 = 46
Solving for x,
4x = 40
x = 10
This means, the width is 10 cm, while the length is 13 cm
Therefore, the dimensions of the rectangle is length 13 cm and width 10 cm
Answer:
a = 7 and c = 12
Step-by-step explanation:
Set up 2 equations and use substitution:
4a + 2c = 52
12a + 4c = 132
In the first equation, c = 26 - 2a
We can plug that into the second equation to solve for a.
12a + 4(26 - 2a) = 132
a = 7
Plug a back in to either original equation to solve for c:
4(7) + 2c = 52
c = 12
Answer:
The x-intercept is at -8 and the y-intercept is at -5.
Step-by-step explanation:
When you simplify 5x + 8y = 40 into y = mx + b form, you get y = -5/8x - 5.
