Answer:
12 inches
Step-by-step explanation:
What information is useful?
Each brick is: 1 1/2 inches long.
There are 8 bricks used.
Let's multiply 1 1/2 x 8 = 12 inches.
You can convert into other metrics but depending on your question it is in inches.
The ordered pair that is the solution to the system of
equations cane be solve by adding the two term
(x+ y=−13)+ (x−y=21) = (2x = 8)
X = 4
Substitute x to the first equation
4 +y = -13
Y = -17
Answer:
Step-by-step explanation:
I'm hoping this is what your equation looks like because it's the one I am going to solve! . Begin by subtracting 2 from both sides to get . To undo that square root we have to square it. But because this is an equation, if we square the left side we also have to square the right side. Squaring the left side leaves us with x - 6, and squaring the right side gives us 16. x - 6 = 16. Add 6 to both sides and x = 22
