Factor using the identity: a3 + b3 = (a + b)(a2 – ab + b2) 8z3 + 27

vivado [14]

Answer: this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Explanation:

Since we have given that

$8z^3+27$

As we know the identity , which says that

$a^3+b^3=(a+b)(a^2-ab+b^2)$

So, we can use this here ,

$8z^3+27=(2z)^3+3^3\\\\=(2z+3)((2z)^2-2z\times 3+3^2)\\\\=(2z+3)(4z^2-6z+9)$

Hence this is our required factor i.e.

$8z^3+27=(2z+3)(4z^2-6z+9)$

Given the length of three sides of a triangle, which is a right triangle?

navik [9.2K]

Pythagoras, cool.
30^2 is 900
15^2 is 225
26^2 is 676
676+225 isn't 900 so it isn't A.

10^2=100
26^2=676
24^2=576
100+576=676 so B is a right angled triangle.

Hope this helps :)

Can someone please please please help with this problem preferably by the end of today? (later is fine too tho)

V125BC [204]

Answer:

Add all of the items, then multiply by 5

Step-by-step explanation:

Why by 5? Well, in order to make

5 cookies per player one batch would be made

so, 10 cookies pp = 2 batches

15 cookies pp = 3 batches

20 cookies pp = 4 batches

and then you would need 4 more to make 2 dozen, so you would then make another batch and have a few extra, but you would have 2 dozen per player!

hope this helps!!

39. Find the length of each arc shown in red. Leave your answer in simplified radical form.

andre [41]

Answer:

The length of the arc shown in red is $\frac{22}{9}\pi\ in$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=4\ in$

substitute

$C=2\pi (4)$

$C=8\pi\ in$

step 2

Find the length of the arc in red

Remember that the length of the circumference subtends a central angle of 360 degrees

by proportion find the length of the arc by a central angle of 110 degrees

$\frac{8\pi}{360}=\frac{x}{110}\\ \\x=8\pi*110/360\\ \\x=\frac{880}{360}\pi\ in$

Simplify

$\frac{880}{360}\pi=\frac{22}{9}\pi\ in$
