12x/15-10x/15
=2x/15 is your answer
Answer:
7.06
Step-by-step explanation:
Write a proportion using similar triangles.
DF / DG = DE / GE
x / 8 = 15 / 17
x = 7.06
Answer:
x^3+5x^2+16x+80
Step-by-step explanation:
You know that you can write your polynom this way : (x-r1)(x-r2)(x-r3) with r1,r2 and r3 the roots so you get :
(x+5)(x+4i)(x-4i)
Simplify (x+4i)(x-4i) with the formula (a-b)(a+b)=a²-b²
so you have (x^2+16)=(x+4i)(x-4i)
Your polynom looks like this :
(x^2+16)(x+5) just expand it
and you get x^3+5x^2+16x+80
WHAT IS THE SQUARE ROOT OF 64? OR RATHER DOES 16 DIVIDE INTO 64?
<em>25 different ways </em>( the answer )
All you have to do is multiple the number by itself
or
<em>Example : </em>
6 backpacks and 3 pencils
6 times 3
18 different combinations :)
