Answer:
P≈28.28cm
d = Diagonal 10cm
Using the formulas
P=4a
d=2a
Solving for P
P=22d=2·2·10≈28.28427cm

Step-by-step explanation:
5x-2y=3 when: y=2x
1. Plug in the y-value (y=2x) into the equation (5x-2y=3). The equation should then look like 5x-2(2x)=3
2. Simplify:
5x-2(2x)=3
5x-4x=3
1x=3
x=3
Check:
5x-2(2x)=3 (plug in the x-value you solved for: 3)
5(3)-2×2(3)=3
15-2×6=3
15-12=3
3=3
Hope this helped !

The value of x from the given expression is 5/6
<h3>Expansion of equation</h3>
Given the expression to expand expressed as:
15 = 3/5(6x + 20)
We are to determine the value of x
15(5) = 3(6x + 20)
Expand
75 = 18x +60
Collect like terms
18x = 75 - 60
18x = 15
x = 15/18
x = 5/6
Hence the value of x from the given expression is 5/6

Answer:
8x + 4y = 12 & y = -2x + 3 are the same equations.
Step-by-step explanation:
To know which choice has the same equation in both forms, we need to transform the standard form into the slope intercept form.
Then, solving for y in the first equation, we get:

It means that 8x + 4y = 12 & y = -2x + 3 are the same equations.
At the same way, we get that:
- 6x + 3y = 18 & y = 2x + 6 are not the same equation:

- 2x + 4y = 8 & y = -2x + 2 are not the same equation:

- 3x + 4y = 12 & y = ¾x + 3 are not the same equation:
