Length of edges in A: length of edges in B = 3:5 The perimeter of A is 345 mm
Work out the perimeter of B in mm.

575 mm

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of sides.

let x be the perimeter of B then by proportion

= ( cross- multiply )

3x = 1725 ( divide both sides by 3 )

x = 575

Then the perimeter of B is 575 mm

no this is a nonlinear negative

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
