Answer:
AD = 13
Step-by-step explanation:
Area of trapezoid ABCD
8x²-8x+2-5+x = 8x² - 7x - 3
Thus, g = 7 and h = 3
Answer:
The solutions are x = 1.24 and x = -3.24
Step-by-step explanation:
Hi there!
First, let´s write the equation:
log[(x² + 2x -3)⁴] = 0
Apply the logarithm property: log(xᵃ) = a log(x)
4 log[(x² + 2x -3)⁴] = 0
Divide by 4 both sides
log(x² + 2x -3) = 0
if log(x² + 2x -3) = 0, then x² + 2x -3 = 1 because only log 1 = 0
x² + 2x -3 = 1
Subtract 1 at both sides of the equation
x² + 2x -4 = 0
Using the quadratic formula let´s solve this quadratic equation:
a = 1
b = 2
c = -4
x = [-b± √(b² - 4ac)]/2a
x = [-2 + √(4 - 4(-4)·1)]/2 = 1.24
and
x = [-2 - √(4 - 4(-4)·1)]/2 = -3.24
The solutions are x = 1.24 and x = -3.24
Have a nice day!
Answer:
He gained 3,650 dollars over 5 years of saving his retirement money
Step-by-step explanation:
Just subtract 5,00 from 8,000 and u get 3,000 so then just add 650 to the 3,000 and thats your answer 3,650!!
A straight line equals 180 degrees, so the 3 angles in the picture need to equal 180.
X + 90 + 25 = 180
x +115 = 180
Subtract 115 from both sides:
x = 65
