Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have
2 x 4k - 2 x 3
which gives you
8k - 6
Answer:
43 - 12y
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
6 • (7 - 3y) + (6y + 1)
Step 2 :
Final result :
43 - 12y
Think: (4)^3 * (x^2)^3, or 64 * x^(2*3), or 64 x^5 (answer)
Answer:
Transitive Propertey
Step-by-step explanation:
Because it has "If" in it.
Answer:
I believe the answer is 166.6 Joules or (if rounding to the nearest whole number) 167 Joules.
Step-by-step explanation:
Here is the formula to find the gravitational potential energy of an object:
U = m * g * h (potential energy equals mass times gravitational acceleration * the height)
The mass is 8.5 kilograms, the height is 2 meters, and Earth's gravitational acceleration is always, no matter the other values or earthly situations, 9.8 m/s.
Now we solve:
8.5 * 9.8 * 2 = 166.6 which is rounded to 167 Joules.
