Can someone please help it’s urgent :( ?

76

Step-by-step explanation:

5x+16 and 9x-32

first we take away 5x from both sides

16=4x-32

Then we add 32

it then becomes

48=4x or 4x=48

We divide 48 by 4 and get 12

To check your answer we plug x back in

5(12)+16=9(12)-32

5(12)+16=76

9(12)-32=76

so x is correct and since this is a square all sides are congruent

So all sides are 76

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
