Answer:

one is using commutative property 4d - 8

another is 2 to power of 4 - 2 to the power of 2

Step-by-step explanation:

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)


Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000


Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.


Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12


Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.

Answers

Answer:

108 degrees

Step-by-step explanation:

By the Exterior Angle Theorem:

(2x + 1) + 63 = 5x -2

2x + 64 = 5x - 2

66 = 3x

22 = x

Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:

5(22) - 2

110 - 2

108

The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)

Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)

Answers

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)
