A student factors a^6 - 64 to (a^2 - 4)(a^4 + 4a^2 + 16). Which statement about (a^2 − 4)(a^4 + 4a^2 + 16) is correct?

Lorico [155]

So that equation was definitely correct...

When you expand the equation in the bracket you'll find out that you'll get a^6 + 4a^4 + !6a^2 - 4a^4 - 16a^2 -64. then your final result will be a^6 - 64

QUESTION IS STATED IN PICTURE DONT FORGET TO ROUND TO THE NEAREST HUNDRETH. USE 3.14 pi IF NEEDED

Anna007 [38]

The area of a circle is given by:

$A=\pi\cdot r^2$

Where r is the circle's radius. In this case we have a diameter of 8cm so the radius 4cm. Using pi=3.14 we have that the area of the circle is:

$A=3.14\cdot4^2=50.24$

So the area is 50.24 cm^2.

If you have the following equation; 4x - 4.5 = 10.73x + 5.7 + 7x, what would you multiply each term by to get rid of the decimal

posledela

Answer:

100

Step-by-step explanation:

You are given the equation

$4x-4.5=10.73+5.7+7x$

There are 5 coefficients:

$4, \ -4.5,\ 10.73,\ 5.7,\ 7$

Two of them are integers

$4,\ 7$

two of them are decimals with one digit after point

$-4.5,\ 5.7$

and one is a decimal with two digits after point

$10.73$

To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:

$400x-450=1,073x+570+700x$
