The center of the circle is (0,-4) and the radius is 8 because the center comes from the (x-_) and (y-_) and the radius is square root the =_
Area of a rectangle = Lenght x width
Lenght = 80 cm
Width = 60 cm
Height = 50 cm
A = 80x 60 = 4800 cm^2
Answer: 2x+3
Step-by-step explanation:
Hello here is a solution :
let A(-6;4) O(0;0) B(x; 0)
i'have : OA² = OB²+AB² ( pytagore theorem)
OA² = (-6-0)² +(4-0)² = 36 +16 =52
OB² = (x-0)² + (0-0)² = x²
AB² = (x+6)² +(0-4)² = x²+12x+36 +16 = x²+12x+52
52 = x² + x²+12x+52
2x² +12x=0
2x(x+6) =0
2x=0 or x+6 = 0
x=0 or x= -6
conclusion : x = -6
if x = 0 i' have not the <span>triangle</span>
An integer between 6.75 and 7.75 would be the whole number greater than 6.75 and less than 7.75: 7.
