-7xy+4x^2-8 and y+1-8x^y
Step-by-step explanation:
Answer:
All of the answers if you consider the dashes both negative and positive, but if they are negative then its the last 3 only.
Step-by-step explanation:
<span>Each Interior Angle = <span>(<span>(Number of Sides -2) • 180 degrees<span>)<span> ÷ (Number of Sides)
Solving for number of sides
</span></span></span></span></span>
<span>Each Interior Angle / 180 = <span>(N -2) <span>/ (N)
144 / 180 = (n-2) / n
144 * n = 180n -360
360 = 36 n
n = 10 the number of sides

7(x+2) = 35
Use the distributive property:
7x + 14 = 35
Subtract 14 from each side:
7x = 21
Divide both sides by 7:
x = 21 / 7
X = 3
The answer is C. 3
