Answer:

130z-3

Step-by-step explanation:

Break down the equation:

(9z^{2}-4)=

9z * 9z= 81z

You can't subtract 4, so I left it at (81z- 4)

(7z^{2}+ 1)=

7z * 7z= 49z

You can't add 1, so I left it at (49z+ 1)

Then Solve:

You can add 81z and 49z.

81z+49z= 130z

-4+1= -3

Hope this helps!

If 900 is shared in the ratio 8:10,find each shared
kirill [66]

Answer:

400 and 500

Step-by-step explanation:

the ratios are 8:10

total ratio = 8+10 = 18

share for the ratio is 8 = 8/18×900

= 0.444444444×900= 400

therefore, share for the ratio of 8= 400

share for the ratio of 10= 10/18×900

= 0.555555555×900=500

therefore, share for the ratio of 10= 500
