<h3>Answer: Choice A) 8</h3>
===========================================================
Explanation:
3D figures can be tricky to visualize when looking at a 2D flat surface.
One way to picture this is to imagine a house. The first floor is what I've highlighted in figure 1 (see attached image below). The second floor is in figure 1, and the third floor is in figure 3.
We have 5 blocks on the first floor, 2 blocks on the second floor, and 1 block on the third floor. This is a total of 5+2+1 = 8 blocks.

Answer:
The answer is neither.
Step-by-step explanation:
We need to solve for y in the equation, 10x-2y= 6.
In other words, we are going to find the slope intercept of that equation.
So we have now have both the equations:
It's not parallel because the slopes aren't the same. It's not perpendicular because when the slope of the equation becomes a negative reciprocal, it still doesn't end up with the same slope as the other equation.
It's neither parallel or perpendicular.
Answer:
a)
b)
c)
Explanation -
a) 2/3 p + 10 = r
Value of r = 22 (given)
2/3 p + 10 = 22
2/3 p = 22- 10
2/3 p = 12
p = 12 × 3 /2
p = 6 × 3
<em><u>p</u></em><em><u>=</u></em><em><u>1</u></em><em><u>8</u></em><em><u> </u></em>
b) (-17) + 5k = t
value of k = 4 (given)
(-17) +5 (4) = t
(-17) + 20 = t
<em><u>3</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>t</u></em><em><u> </u></em>
c) 0 = 5p - 3b
b= 2 (given)
0 = 5p - 3(2)
0 = 5p - 6
6 = 5p
<em><u>6</u></em><em><u>/</u></em><em><u>5</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>p</u></em>
