Answer: x= -9,8

Step-by-step explanation:

x=?

y=0

y=x^2+x-72

0=x^2+x-72

0=(x+9)(x-8)

x+9=0 x-8=0

-9 -9 +8 +8

x= -9 x=8

Answer:

7. C(N(h))=33hx+460h

8. about $13.94 is the cost

Step-by-step explanation:

7. C(x)=(33x+460)(N(h))=(N(40)h)--C(x)=(33x+460)(40h)--C(x)=1320hx+18400h--simplified to C(N(h))=33hx+460h

8. C(N(10))=33(10)x+460(10)--C(N(10))=330x+4600--4600/330=about13.94

Which expression can be used to solve 3/5 ÷ 7/10

marusya05 [52]

Answer:

Step-by-step explanation:

3/5 divided by 7/10

You use KCF

KCF stands for keep change flip

So it would be 3/5x10/7

3 10 15

_ x _ = _

5 7 7

you need to simplify it so the 5 in 3/5 would be a 1 and the 10 in 10/7 would be 5

Can someone help please

yanalaym [24]

Step-by-step explanation:

a) The volume of the prism is

$V = (n^2 - 1)×(n^2 - 1)×(5n)$

$\:\:\:\:= (n^4 - 2n^2 + 1)(5n)$

$\:\:\:\:=5n^5 - 10n^3 + 5n$

b) If the dimensions L of the prism are tripled, the new volume will be

$V' = (3L)^3 = 27L^3 = 27V$

so it will increase by a factor of 27.
