Answer:
The variable "a number" stands for 9.
Step-by-step explanation:
Rewrite the problem as 2 * (6 + x) = 30
Divide 30 into 2. 30/2 = 15
That means that the variable that is added to 6 must make the number 15.
15 - 6 = 9
The variable x is 9 so the equation would be:
2 * (6 + 9) = 30
The answer is -16. Here's the explanation:
3 x - 10 = 5x + 22
3x - 5x = 22 + 10
-2x = 32
x = -16.
I hope this helped you!!!!!! :)
Answer:
(-3,0)
Step-by-step explanation:
To find the x-intercept set y to 0,
x^2 + 6x + 9 = 0 Now you have a quadratic equation, so you can solve it
(x + 3)(x + 3 ) = 0
x + 3 = 0
x = -3
To calculate the volume of the rectangular prism and the triangular prism you will multiply the area of the base by the height of the prism.
1. V = BH
V = lwH
12 x 8 x 4
V = 384 cubic inches
2. V = BH
V = 1/2bhH
1/2 x 12 x 2 x 18
V = 216 cubic feet
