Rationalize the expression and simplify. <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B4%2Bh%7D-2%20%7D%7Bh%7D"

MAXImum [283]

You multiply by the conjugate to both the denominator and numerator.
After that you can simplify by canceling the 4 and then you are able to simplify the (h) as well.

Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.

DanielleElmas [232]

Answer: Our required answer will be

$11x^2y^3-4xy^2$

Step-by-step explanation:

Since we have given that

$(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)$

We need to get the difference:

1) We first open the second bracket and make appropriate change in signs :

$4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y$

2) Gather the like terms together :

$4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2$

Hence, our required answer will be

$11x^2y^3-4xy^2$

Which expression is equivalent to 8a +14

andrey2020 [161]

Answer:

2(4a + 7)

Step-by-step explanation:

2 to the 4 and 7

This would give you 8a + 14 because 2 times 4 is 8, and 2 times 7 is 14.

Hope this helps.
