Answer:

B. 16 square meters

Step-by-step explanation:

To find the surface area of a square pyramid use this equation: b² + 4(bh/2). b and h will be 2 & 3 respectively.

2² + 4((2 * 3)/2)

<em>First, let's do the work inside the parentheses. We can cancel out the multiplication by 2 and the division by 2, so the right side (by that I mean to the right of the plus sign) just becomes 4(3).</em>

2² + 4(3)

<em>Now, multiply 4 by 3 to get 12.</em>

2² + 12

<em>Next, square 2 to get 4.</em>

4 + 12

<em>Lastly, add 4 and 12 to get 16.</em>

16 m²

After doing the math, I can deduce that the area of this square pyramid is 16 m² (square meters), which is B.

Solve the systems of equations 6x+3y=9 2x+3y=1
patriot [66]
Solve by elimination.
The goal is to cancel out one of the variables in order to easily solve for the other variable.

Do this by changing the equations so that the coefficients of either x or y add up to 0.

Notice the coefficients of y are 3 and 3, if we make one of them negative then they add up to 0. 3+ (-3) = 0

Multiply 2nd equation by -1.

6x +3y = 9
-2x -3y = -1
__________
4x +0y = 8

Solve for x
4x = 8
x = 8/4 = 2

Plug x=2 back into one of original equations to find y.
---> 2(2) + 3y = 1
---> 4 + 3y = 1
---> 3y = -3
---> y = -1

Therefore solution is (2,-1)

5) Find the distance between -9 and 12 on a number line.​
kati45 [8]

Answer: Hope this helps!!!

Step-by-step explanation:Absolute Value: You need to find how far away both numbers are from zero, then add these values together to see how far apart these numbers. The absolute value of nine, |-9| is 9, and |12| is 12. This means that the nine is nine spots away from zero, and twelve is twelve spots from zero. This means that the numbers are 20 units from each other.

Distance -9 is from 12 You need to find how much of an increase from nine you need to reach the twelve. So -9 + ? = 12. What number can you add to equal twelve? You can add 20 to make the equation true. (? = 20) The distance from -9 to 12 is a positive 20.

Distance from 12 to -9 This is similar to the previous example. What number can you insert to make the 12 equal the negative nine? 12 - ? = -9. The number would be -20, which means that 12 is 20 spots away from the negative nine, as it took at negative twenty to get us to the negative nine.
