Step-by-step explanation:

Her brother is 9 and she is 14.

say she is 14, 14+2=16 a perfect square.

14-10=4 which is the square root of 16.

So she is 14 and her brother is 9.

(He is a perfect square too, by the way.)

Answer: The value of x is 5.970.

Step-by-step explanation:

Given: The square has sides length of X cm.

Let r be the radius of the circle.

The square fits exactly inside a circle with each of the vertices being on the circumference of the circle.

Then diagonal of square = diameter of circle

i.e. $\sqrt{2}x= 2r$ [Diagonal of square = $\sqrt{2}$ (side)]

i.e. $r=\dfrac{x}{\sqrt{2}}$

area of circle = $\pi r^2$

i.e. $56=\frac{22}{7}(\frac{x}{\sqrt{2}})^2$

$56=\frac{22}{7}\times\frac{x^2}{2}\\\\\Rightarrow\ x^2= \dfrac{7}{11}\times56\\\\\Rightarrow\ x^2=35.636\\\\\Rightarrow\ x=\sqrt{35.636}\approx5.970$

Hence, the value of x is 5.970.

a) <u>n² + 6 </u>

~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.

If n = 1, first term = 1² + 6 = 7
n = 2, second term = 10
n = 3, third temm = 15
n = 4, fourth term = 22
n = 10, tenth term = 106

b) <u>3n²</u>

If n = 1, first term = 3
n = 2, second term = 12
n = 3, third term = 27
n = 4, fourth term = 48
n = 10, tenth term = 300
