8a² - 4b + 7a² and 5(3a² - 2b) + 6

First, simplify the expressions.

1) 8a² - 4b + 7a²

Add like terms.

15a² - 4b

2) 5(3a² - 2b) + 6

Distribute 5 by multiplying the number to each terms inside the parenthesis.

15a² - 10b + 6

15a² - 4b ≠ 15a² - 10b + 6

Solution: The expressions are not equivalent.

Help pls do allll 6 questions... with steps
BaLLatris [955]
You just want to simplify right?!

45. (a^2b^3)(ab)^-2
= (a^2b^3)(a^-2b^-2)
= b
46. (-3x^3y)^2(4xy^2)
= (-9x^6y^2)(4xy^2)
= -36x^7y^4
47. 3c^2d(2c^3d^5) / 15c^4d^2
= 6c^5d^6 / 15c^4d^2
= 2/5c1/4x^4
48. -10g^6h^9(g^2h^3) / 30g^3h^3
= -10g^8h^12 / 30g^3h^3
= -1/3g^5h^9
49. 5x^4y^2(2x^5y^6) / 20x^3y^5
= 10x^9y^8 / 20x^3y^5
= 1/2x^6 1/3y^3
50. -12n^7p^5(n^2p^4) / 36n^6p^7
= -12n^9p^9 / 36n^6p^7
= -1/3n^3p^2

(Sorry it’s messy it’d look better if my phone could actually put the numbers to the power)
