I WILL MARK BRAINLIEST

Mathematics
1 answer:

7 0

Answer:

I think the answer would be the very first one.

they all need to have '' ( ) '' in them.

if a number is outside of that, it needs to at least have a letter beside the number

here's an example

Factored form:

2x(x + y)

not factored:

2(x - y)

but for the first one, it's correct from the rest of them.

Need HELP!!! For all, I’m truly confused
Nataliya [291]

Answer:

Step-by-step explanation:

The figures dont have enough letters to explain step by step all the exercises.

Bread 1:

The horizontal lines are parallels so both angles must be the same

2x + 21 = 4x - 17

21 + 17 = 4x - 2x

38 = 2x

x = 19

Bread 2:

Angles sum 180°

3y - 5 + 2y - 25 = 180

5y - 30 = 180

5y = 180 +30

5y = 210

y = 42

Bread 3:

Angle ABC is the same as the other 2, since x = 19

ABC = 2x + 21

ABC = 2 * 19 + 21

ABC = 59

Bread 4:

Angle ABC is the same as 3y - 5, y = 42

ABC = 3y - 5

ABC = 3 * 42 -5

ABC = 121

Bread 5:

Angles must be the same

5x - 14 = 2x + 13

5x - 2x = 13 + 14

3x = 27

x = 9

Bread 6:

Angle ABC = 5x - 14 , x = 9

ABC = 5 * 9 - 14

ABC = 31

If you need to understand why the angles must be the same just comment and I will give you more details
