We can find the 15.2% of 185 pounds by dividing the weight by 15.2% in its decimal form:
therefore, there are 27.7 pounds of fat
Answer:-2x^2(2-1)
Step-by-step explanation:
-4x^2 + 2x^2=-2x^2(2 - 1)
Answer:
its altitude is 8 cm
Step-by-step explanation:
1/2× base ×altitude =48
1/2×12× al =48
6×al =48
al = 8
16. 5x^3 y^-5 • 4xy^3
20x^4y^-2
20x^4 • 1/y^2
=20x^4/y^2
17. -2b^3c • 4b^2c^2
= -8b^5c^3
18. a^3n^7 / an^4 (a^3 minus a = a^2 same as n^7 minus n^4 = n^3)
=a^2n^3
19. -yz^5 / y^2z^3
= -z^2/y
20. -7x^5y^5z^4 / 21x^7y^5z^2 (divide -7 to 21 and minus xyz)
= -z / 3x^2
21. 9a^7b^5x^5 / 18a^5b^9c^3
=a^2c^2 / 2b^4
22. (n^5)^4
n ^5 x 4
=n^20
23. (z^3)^6
z ^3 x 6
=z^18
Step-by-step explanation:
