Answer:
w = -3
Step-by-step explanation:
8w + 12 = -12
use inverse operations:
8w + 12 = -12
-12 -12
8w = -24
/8 /8
w = -3
Answer:
No real solutions
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
D = b² - 4ac
Plug in b, a, and c:
D = b² - 4ac
D = (8)² - 4(1)(20)
D = 64 - 80
D = -16
Since the discriminant is negative, there are no real solutions
Answer:
Distance traveled by the snowball = 45feet
Step-by-step explanation:
The distance traveled by the snowball = distance of hypothenus for both Right angle triangle
1st pythagoras =
X² = 20² + 15²
X = (20² + 15²)¹/² = 25 feet
2nd pythagoras =
X² = 16² + 12²
X = (16² + 12²)¹/² = 20 feet
Distance traveled by the snowball = 20 + 25 = 45feet
m∡A = 70º
1) Considering that the Sum of the interior angles within a triangle is always 180º
2) We can write the following, and solve for x
x+80 + x +80 +40 = 180
2x +160 +40 = 180
2x + 200 = 180
2x =180-200
2x= -20
x=-10
3) So since angle A = x +80, we can plug it into that the value of x
m∡A = x +80º
m∡A=-10+80
m∡A = 70º
