Answer:
Step-by-step explanation:
<u>Use Pythagorean:</u>
<u>Substitute values of a and b and solve for c:</u>
- 3² + 14² = c²
- 205 = c²
- √205 = c
- c = 14.3 cm
2(x-6y+4z=2)
2x+4y-8z=16
2x-12y+8z=4
2x+4y-8z=16
4x-8y=20
x-2y=5
4x-8y=20
-4x+8y=-20
infinite many solutions
Answer:
John should build the box 3 cm high.
Step-by-step explanation:
John should build the box 3 cm high because to find the volume you must do length x width x height. To find this you have to multiply the length x width. In this problem 6 would be the length and 2 would be the width. After multiplying those you get 12. You then have to find what number multiplies with 12 to get 36, which is 3. Hope this helped!
