Positive because a negative and a negative will always make a positive
Answer:
(4,0)
Step-by-step explanation:
4x+2y=16
-4y+x=4
Multiply the first equation by 2
2(4x+2y)=16*2
8x +4y = 32
Add the 2nd equation
8x +4y = 32
x -4y =4
--------------------
9x =36
Divide each side by 9
9x/9 = 36/9
x=4
Now solve for y
-4y +x =4
-4y +4 = 4
Subtract 4 from each side
-4y +4-4=4-4
-4y =0
Divide by -4
-4y/-4 =0/-4
y=0

Answer:
The prism has a volume about 340 cubic centimeters larger than the cone.
Step-by-step explanation:
<h3><u>Cone</u></h3>
<u />
<u>Formulas</u>


where:
- r = radius of circular base
- h = height perpendicular to the base
Given:
Substitute the given values into the formulas:


<h3><u>Prism</u></h3>
<u>Formulas</u>
<u />



Given:
- Height of triangular base = 10 cm
- Base of triangular base = 8 cm
- Height of prism = 10 cm
Find the <u>area of the triangular base</u> of the prism:

Find the third edge of the triangular base by using <u>Pythagoras Theorem</u>:

Use the found values and the formulas to find the surface area of volume of the prism:


<h3><u>
Conclusion</u></h3>
The surface area and volume of the prism is <u>larger</u> than that of the cone.
<u>Difference between surface areas</u>:
388.1 - 91.5 = 296.6 ≈ 300 cm²
<u>Difference between volumes</u>:
400 - 56.5 = 343.5 ≈ 340 cm³
Therefore:
- The prism has a surface area about 300 square centimeters larger than the cone.
- The prism has a volume about 340 cubic centimeters larger than the cone.
