Answer:
c
Step-by-step explanation:
x²+y²+4x+6y=0
compare with x²+y²+2gx+2fy+c=0
centre is (-g,-f)=(-2,-3)
radius=√(g²+f²-c)=√((-2)²+(-3)²-0)=√13
Answer:
x=5
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
The box is a right angle which is 90 degrees
60+6x+90 = 180
Combine like terms
150+6x= 180
Subtract 150 from each side
150-150+6x = 180-150
6x = 30
Divide by 6
6x/6 =30/6
x = 5
T = 5.34 + 0.78m
T = 5.34 + 0.78 * 5
T = 5.34 + 3.9
T = 9.24
Tina was charged $9.24 at the car wash for 5 minutes.
Answer:
what the question
Step-by-step explanation:
A^2 + b^ = c^2
c is the longest side of the triangle
a and b are the other two sides
So the given are the hypotenuse leg, and one of the other legs
So
a= ?
b= 12
c= 14
a^2+12^2=14^2
a^2+144=196
-144 -144
a^2=52
So we find the square root of 52
Which is 7.211 which you can round to 7.21 or 7.2
