Answer:

Ext=2x

Int=7x

Int+ext=180

2x+7x=180

9x=180

x=20

Ext=2×20=40

No of sides =360/40

=9 sides.

Solve the equation: p2 - 4p + 4 = 0.

iragen [17]

Perfect square trinomial

$\boxed{ a^2 \pm 2ab+b^2 = (a \pm b)^2 }$

Using the perfect square trinomial

$p^2 - 4p + 4 = 0$

$p^2 - 2(2p) + (2)^2 = 0$

$(p-2)^2 = 0$

$(p-2) = 0$

$p = 2$

How do you solve this? Thank you

Answer:

x = 28y

Step-by-step explanation:

1. To solve this equation, we have to try to isolate the variable x/solve for x.

2. (Solving)

Step 1: Simplify.

$\frac{1}{4}x + 2y = 9y$

Step 2: Subtract 2y from both sides.

$\frac{1}{4}x + 2y - 2y = 9y - 2y$
$\frac{1}{4}x = 7y$

Step 3: Multiply both sides by 4.

$\frac{1}{4}x * 4 = 7y * 4$
$x = 28y$

Therefore, x = 28y! I hope this helped you out.
