A square with a side length of 4 would have an area of 16 because 4x4 equals 16.
Answer:
n = 23°
Step-by-step explanation:
Angles that form an "x" shape are called vertical angles.
In this case, ∠MRP and ∠ QRN are vertical angles.
Vertical angles are always equal.
Therefore, m∠MRP = m∠QRN
Substitute
m∠MRP = m∠QRN
35° = 2n - 11°
Add 11° to both sides of this equation
46° = 2n
Divide both sides of the equation by 2
23° = n
n = 23°
Hope this helps :)

Answer:
3
Step-by-step explanation:
Let x represent the number. The problem statement tells you ...
2/3(3x +6) = 10
2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

<em>Comment on the solution</em>
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
