Plz help me out here

1. 3cm

2. 6m

Step-by-step explanation:

If all angles are right angles, it means that both lengths on the right side add up to the length on the left side.

For the first one, the length on the left is 7cm, and there are two lengths on the right: 4cm and an unknown we can call 'x'.

We know that both of the right lengths add to the left length so we can represent this as so:

4+x=7

To solve for x we can minus 4 from both sides:

x+4-4 = 7-4

x = 7 -4

x = 3cm

We can solve the second one in a similar fashion:

x + 6 = 12

x + 6 - 6 = 12 - 6

x = 12 - 6

x = 6m

Hope this helped!

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
