Answer:
3.87 ft = Length of unknown side of the right triangle.
Step-by-step explanation:
Given,
Hypotenuse = 4 ft
Base = 1 ft
Altitude = x
Hypotenuse² = Base² + Altitude²
4² = 1² + x²
4² - 1² = x²
16 - 1 = x²
15 = x²
√15 ft = x
3.87 ft = x

Answer:
y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Step-by-step explanation:
Solve for y:
y^2 + y - 7 = 0
Add 7 to both sides:
y^2 + y = 7
Add 1/4 to both sides:
y^2 + y + 1/4 = 29/4
Write the left hand side as a square:
(y + 1/2)^2 = 29/4
Take the square root of both sides:
y + 1/2 = sqrt(29)/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
y = sqrt(29)/2 - 1/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
Answer: y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Answer:
x = 0
Step-by-step explanation:
27 - 3x = 3x + 27
- 3x - 3x = 27 - 27
- 9x = 0
x = 0
This is because the lines make it opposite. So the opposite of -11 is 11.
