The answer would be A. Commutative property of addition
Move constant to the right-hand side and change its sign
2x^2 + 8 = -2 + 7
-2 + 7 = 5
Divide both sides of the equation by
x^2 + 4x = 5/2
Add (4/2^2) to both sides of the equation
x^2 + 4x + (4/2)^2 = 5/2 + (4/2)^2
factor the expression
(x + 4/2)^2 = 13/2
reduce the fraction by 2
(x + 2)^2 = 13/2
now solve equation for x
126/3 = 42 calories per 1/4 cup. This 2 x 42 calories (2 quarters = 1/2 cup) = 84 calories.
Answer:
Sí, 7 es un número natural
Step-by-step explanation:
Answer:
No, it cannot have angles that measure 95°, 67°, 105°, 95°, and 177°.
Step-by-step explanation:
S = (n-2) * 180
A pentagon has 5 sides, so substitute n for sides (n = 5)
s = 5-2) * 180 = 540°
95° + 67° + 105° + 95° + 177° = 539°
Hope that Helps!
