The correct Option is (A) 35x^3 - 16x^2 + 44x - 48

Explanation: The product of the polynomials (5x^2 + 2x +8)(7x-6) is:

(5x^2)(7x-6) + 2x(7x-6) +8(7x-6)

35x^3 -30x^2 + 14x^2 - 12x + 56x - 48
35x^3 - 16x^2 + 44x - 48 (Option A)

Answer:

$about \: 1.01551$

Step-by-step explanation:

No it isn't, because:

${1.08}^{ \frac{1}{5} } = { \frac{108}{100} }^{ \frac{1}{5} } = { \frac{27}{25} }^{ \frac{1}{5} } = \sqrt[5]{ \frac{27}{25} } = 1.01551$

How do I solve this using the Pythagorean theorem

charle [14.2K]

Answer:

x=3

Step-by-step explanation:

First would need to convert the radical into a number.

And since if you have a perfect square of a radical it goes outside the square root sign, you would take the 3 and square it to make 9 and then take the 2 inside the square root sign and multiply so you have the square root of 18|

Since we have $\sqrt{18}$ as the Leg c we would need to square it, squaring a square root sign would just cause them to be cancelled out and you being left with 18, afterwards find the square of 3, which is 9
