Using a system of equations, it is found that the equation that could be used to find the value of b is given by:

3×4−8=b

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

Fatima has 3 packs of batteries. Each pack contains 4 batteries, hence:

b = 3 x 4

She gives her brother 8 batteries to put in his toy robot, hence:

b = 3 x 4 - 8

Which means that the first expression is correct.

Find the perimeter of rectangle whose length is 40 and the diagonal is 41 cm<br>​
Bond [772]

Answer:

<h2>              P = 98 cm</h2>

Step-by-step explanation:

Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.

L=40\, cm\\D=41\,cm\\W=\ ?\\\\W^2+L^2=D^2\\\\W^2+40^2=41^2\\\\W^2+1600=1681\\\\W^2=81\\\\W=9

Perimeter:

P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98
