Answer:
1. <u>+12x</u> and <u>15</u>
2. <u>14x</u>
3. <u>2</u>
Step-by-step explanation:
Step 1: Distribute -3
To distribute -3, you would multiply both -4x and -5 by -3, changing them to 12x and 15
Step 2: Combine 12x and 2x
Then you would combine like terms, meaning that you would add 12x and 2x, creating 14x.
Step 3: Combine 15 and -13
You would finish combining like terms by adding 15 to -13, creating 2
Answer:
2,500 ÷ 10
Step-by-step explanation:
Let's evaluate each expression one after the other and find out what they both gives us, then we'd now pick or select the one that doesn't give the required answer.
For 2,500 × 10
2500*10 = 25000
For 250,000 ÷ 10
250000/100= 25000
For 2,500 ÷ 10
2500/10= 250
So from the look of the results,
The one that gave us the odd result is
2,500 ÷ 10, and that's our answer.
j^3
_______
4^2 h^4
when you have negatives, you want them to be positive. To do that you need to convert it into a fraction
Answer:
Step-by-step explanation:
Answer:
V ≈ 62.83
Step-by-step explanation:
<u>Cylinder Formulas in terms of r and h</u>
Calculate the volume of a cylinder:
V = πr2h
Calculate the lateral surface area of a cylinder (just the curved outside):
L = 2πrh
Calculate the top and bottom surface area of a cylinder (2 circles):
T = B = πr2
Total surface area of a closed cylinder is:
A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
Solution
V=πr 2h = π · 22 · 5 ≈ 62.83185
Therefore, the volume of the cylinder in the nearest tenths is V ≈ 62.83
