Answer:
Yes, because by dividing x by his equivalent y, you find a constant of proportionality being 10.
x / y = 10
Step-by-step explanation:
20 / 2 = 10
50 / 5 =10
60 / 6 = 10
70 / 7 = 10
Answer:
n+4=32
Step-by-step explanation:
The initial number n gets additional 4 students making the new total number of students to be 32. Therefore, this situation can be represented as
n+4=32
To get the actual number of students before the additio, we make n the subject of formula hence
n=32-4
n=28
Therefore, the initial number was 28 and the equation is n+4=32
Since no choices were provided, the equation that can be modified is n+4=32
Answer:
3x(x2 + 4)
Then use the distributive property
SO the final answer would be: 3x^3 +12x

Answer:
<em>AB = 7.35 cm</em>
Step-by-step explanation:
From the attachment,
In ΔDEF,
DF = GH-(GD+FH) = 6 - (2+3) = 1 cm
DE = 2+3 = 5 cm (sum of two radius)
Applying Pythagoras theorem,
![EF=\sqrt{DE^2-DF^2}=\sqrt{5^2-1^2}=\sqrt{24}=2\sqrt6](https://tex.z-dn.net/?f=EF%3D%5Csqrt%7BDE%5E2-DF%5E2%7D%3D%5Csqrt%7B5%5E2-1%5E2%7D%3D%5Csqrt%7B24%7D%3D2%5Csqrt6)
In ΔCDI,
DI = GH-(GD+IH) = 6 - (2+1.5) = 2.5 cm
CD = 2+1.5 = 3.5 cm (sum of two radius)
Applying Pythagoras theorem,
![CI=\sqrt{CD^2-DI^2}=\sqrt{3.5^2-2.5^2}=\sqrt6](https://tex.z-dn.net/?f=CI%3D%5Csqrt%7BCD%5E2-DI%5E2%7D%3D%5Csqrt%7B3.5%5E2-2.5%5E2%7D%3D%5Csqrt6)
AB = EF + CI = ![2\sqrt6+\sqrt6=3\sqrt6=7.35\ cm](https://tex.z-dn.net/?f=2%5Csqrt6%2B%5Csqrt6%3D3%5Csqrt6%3D7.35%5C%20cm)
