Answer:
box number 4 the last box
Step-by-step explanation:
because 5 x 5 = 25 and 25 x 5 = 125
To complete the square the formula is (b/2)^2 so I’d say the answer would be 82 or the square root of 82
Answer:
–1 maybe
Step-by-step explanation:
maybe maybe maybe
Answer:
180degreesStep-by-step explanation:
Given the complex value
z² = -81i
z = (-81i)^1/2
Get the argument of -81i
theta = arctan(y/x)
theta = arctan(-81/0)
theta = -90degrees
theta = -π/2
Since tan is negative in the secind quadrant
theta = π - π/2
theta = π/2
According to demoivres theorem
theta = 1/2 * π/2
theta = π
theta = 180degrees
Answer:
x = 7
because PQ is an angle bisector
=> RQ/PR = QS/PS
<=> (x - 3)/x = 8/14 = 4/7
<=> 7(x - 3) = 4x
<=> 7x - 21 = 4x
<=> 3x = 21
<=> x = 7
