4-4[6+2n]=-28 I need help with this

1 answer:

4 0

Multiply the term in parentheses by its coefficient:

$4(6 + 2n) = 4 * 6 + 4 * 2n = 24 + 8n$

$4 - (24 + 8n) = -28$

$4 - 24 - 8n = -28$

Combine like terms:

$-20 - 8n = -28$

Add 20 to both sides:

$-8n = -8$

Divide both sides by -8 to get n by itself:

$n = 1$

The value of n is 1.

Li Ping says a square with 3 inch sides has greater area than a parallelogram that is not a square but has sides that have the s

Kipish [7]

Answer:

Li Ping's statement makes sense.

Step-by-step explanation:

The area of a square with side lengths a inches is given by, $A_1 = a^{2}$ .

Now, the area of a parallelogram with equal sides a inches, which is not a square is given by, $A_2 = ah$ , where, h is the perpendicular distance between the opposite sides.
