Answer:
-8 degrees
Step-by-step explanation:
-4 minus 7 degrees add 3 degrees
For this case we have the following expression:
-9x ^ -1y ^ -1 / -15x ^ 5 y ^ -3
For power properties we have:
-9x ^ (- 1-5) y ^ (- 1 - (- 3)) / - 15
Rewriting we have:
9x ^ (- 6) y ^ (- 1 + 3) / 15
3x ^ (- 6) y ^ (2) / 5
3y ^ 2 / 5x ^ 6
Answer:
3y ^ 2 / 5x ^ 6Note: answer is not between the options. Rewrite the expression again, or the options.
(-5a)(-3a ²)
=
15a³
-5 x -3 = 15 ( negative times negative = positive)
a x a² = a³ ( when multiplying exponents, you add the exponents together )
You can't write expanded form in three ways, but you can write that number in expanded form AND two other ways, one you just listed.
Word: thirty seven thousand, nine hundred seventeen thousand, five hundred forty five
Expanded: 30,000,000 + 7,000,000 + 900,000, 10,000 + 7,000 + 500 + 40 + 5
Standard: 37,917,545
The nearest whole number is 11 and the nearest tenth is 11.4. So your answer is 11.4
