Answer:
Step-by-step explanation:
x^2 + 10x + 5 - 30 = 0
x^2 + 10x - 25 = 0
x^2 + 10x = 25
x^2 + 10x + 25 = 25 + 25
(x + 5)^2 = 50 <====

though this is difficult i know you would get it. Anyhow im real tired... will solve later... gl
<span>y= -x^2 + bc + c represents a vertical parabola that opens down. As x approaches either + or - infinity, the function approaches - infinity. Imagine an upside down parabola; doing so will confirm this answer.

Answer:
x = 76°
z = 14°
y = 42°
Step-by-step explanation:
48 + 2x = 180° because these three makes a straight line
2x = 180 - 48
2x = 132
x = 76°
x + z = 90° because these two angles are complementary angles since we know the value of x
76 + z = 90°
z = 90 - 76
z = 14°
48° + y = 90° because these two angles are complementary angles
y = 90 - 48
y = 42°
