Answer:
-8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x+2+x=−22
(2x+x)+(2)=−22(Combine Like Terms)
3x+2=−22
3x+2=−22
Step 2: Subtract 2 from both sides.
3x+2−2=−22−2
3x=−24
Step 3: Divide both sides by 3.
3x
3
=
−24

x=−8
Answer:
12
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 9)² + (y - 4)² = 36 ← is in standard form
with r² = 36 ⇒ r = 
= 6
diameter = 2 × r = 2 × 6 = 12
Hello from MrBillDoesMath!
Answer:
6x
Discussion:
7x = 7 times x
x = 1 times x
So both terms are "like" terms in x:
7x - x = (7-1)x = 6x
Thank you,

Answer:
150.72 cm^2
Step-by-step explanation:
The blue area has an angle of 120 degrees, and 120/360 = 1/3, which shows that the blue area is 1/3 of the circle. In that case, the blue area is just 144pi/3. That simplifies to 48 pi.
48*3.14 = 150.72
