Answer:
256 sq cm
Step-by-step explanation:
cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.
The cross-section described is shown below.
The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.
A=lw
=(16cm) (16cm)
=256 sq cm
So, the area of the cross-section is 256 sq cm.

Once upon a time there was a surprise for a girl named Cassy ,her 4 friends ordered a pie because it was a surprise pie party. Only 1 out of the 4 got to eat the pie since they all wanted to play with the pie pinata. Hope this helped :)
E. 5x+3 = 28
5x = 28 - 3
Divide by 5
Final answer = 5
F. 3x-9 = 18
3x = 18 + 9
18 + 9 = 27
Divide by 3
Final answer: 9
G. 8x-1=7
8x = 7 + 1
7 + 1 = 8
8x = 8
Divide by 8
Final answer: 1
H. 3x+5 = 10
3x = 10 - 5
10 - 5 = 5
Divide by 3
Final answer: 5/3
i. 13 + 7x = -1
7x = -1 - 13
-1 - 13 = -14
Divide by 7
Final answer: -2
j. 14 = 3x + 5
-3x + 14 = 5
-3x = 5 - 14
-3x = -9
Divide by - 3
Final answer: 3
K. 4x - 7 = -13
4x = -13 + 7
4x = -6
Divide by 4
Final answer: -3/2
l. -3 = 2x+ 9
-2x - 3 = 9
-2x = 9 + 3
9 + 3 = 12
2x = 12
Divide it by -2
Final answer: -6
Answer:
A. (0, 6) and (−2, 0)
Step-by-step explanation:
The given equations are:
and
We equate the two equations to find their point of intersection;
We equate everything to zero to get;
When x=0, y=3(0)+6=6
One solution is;
(0,6)
When x=-2,
y=3(-2)+6=0
Another solution is;
(-2,0)
