Step-by-step explanation:
Well, Let's find out!
Gloria says,
2(3x+6)-9x=3*4
By using distributive law
6x+12-9x=12
12-3x=12
-3x=12-12
-3x=0
x=0/-3
So she is not correct
Answer:
Step-by-step explanation:
Use “D = R x 2”, in which "D" equals diameter and "R" equals radius, to solve for the diameter using the numbers you got earlier. Then use “C = pi x D”, in which "C" equals circumference, to solve for the circumference.
Answer:
226.22 in^2
Step-by-step explanation:
Given data
Height l= 6in
Diameter= 12in
Radius= 12/2= 6in
The expression for the total surface area of a cone is given as
TSA= πrl+πr^2
substitute
TSA= 3.142*6*6+3.142*6^2
TSA= 113.112+113.112
TSA= 226.22 in^2
Hence the TSA is 226.22 in^2
Answer:
(0, 12)
Step-by-step explanation:
To find the y-intercept we just plug in x = 0 into the equation.
2(0) + 3y = 36
3y = 36
y = 12 which means the y-int. is (0, 12)
If 9 − 3x < 54 then the following x > -15 must be true.
Inequalities is an expression used to show the non equal comparison of two or more variables.
Given the inequality:
9 − 3x < 54
Subtracting 9 from both sides of the equation:
9 - 3x - 9 < 54 - 9
-3x < 45
Dividing both sides of the equation by -3:
-3x/-3 < 45/-3
x > -15
If 9 − 3x < 54 then the following x > -15 must be true.
