The first condition is for the perimeter of the equation so:

P=2a+b=15.7

Now the secon condition is that the sum of two sides should be:

\begin{gathered} a+b>b \\ b+b>a \end{gathered}

so the negative option and 0 don't make sence dor a distance, then we try with the value of b=0.5

So in the first equation will be:

\begin{gathered} 2a+0.5=15.7 \\ 2a=15.2 \\ a=7.6 \end{gathered}

So the condition:

\begin{gathered} b+b>a \\ 0.5+0.5>7.6 \end{gathered}

this is false, so the solution is

NNADVOKAT [17]
Q1) £16.50 x 1.12 = £18.48
Q2)

Find the series shown.
solmaris [256]

Answer:

C 11+13+15+17+...

Step-by-step explanation:

Consider the series

\sum\limits_{n=3}^{\infty}(2n+5)

The nth term of series is a_n=2n+5

The bottom index tells you that n starts changing from 3, so

a_3=2\cdor 3+5=11\\ \\a_4=2\cdot 4+5=13\\ \\a_5=2\cdot 5+5=15\\ \\a_6=2\cdot 6+5=17\\ \\...

Thus, the sum of all terms is

11+13+15+17+...
