Answer:
No
Step-by-step explanation:
I'm not quite sure what a ratio table is, but I can explain it the way I understand it.
The initial ratio is 10:8 which is 1.25 as a decimal.
Now let's add five to each number to represent the kids joining the class, this will result in the following:
15:13 which is 1.153846154 as a decimal.
Therefore, the ratio doesn't stay the same just because you added the same number of people to each group.
Hope this helps :)
X^2(x+2)-4(x+2)
(x^2-4) (x+2) = 0
do you have to keep going/?

Answer:
7.48m (3s.f.)
Step-by-step explanation:
Let the missing side be x m.
Applying Pythagoras' Theorem,
x² +5²= 9²
x² +25= 81
x²= 81 -25 <em>(</em><em>-25</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
x²= 56


x= 7.48 (3 s.f.)
∴ The missing side is 7.48 m (3s.f.)
