Answer:
x = 7 and x = -1
Step-by-step explanation:
<u>Step 1: Factor</u>
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
<u>Step 2: Solve for x</u>
(x - 7)(x + 1) = 0
x - 7 = 0 and x + 1 = 0
x - 7 + 7 = 0 + 7 and x + 1 - 1 = 0 - 1
x = 7 and x = -1
Answer: x = 7 and x = -1
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable
So your Answer is x = 2 Hope this helps :)

Answer:
B
Step-by-step explanation:
No because the arcs do not have the same measure. The measure of one arc is 142 and the other is 140.
Step-by-step explanation:
x and 63° are subtended by the same arc, therefore their measures will be equal.
Therefore, x = 63°
The diagonal of length 2r forms the hypotenuse of a right angled triangle with one leg ( the width of the rectangle) = x. So by Pythagoras:-
(2r)^2 = h^2 + x^2 where h = height of the rectangle
h^2 = 4r^2 - x^2
h = √ (4r^2 - x^2) answer
