Is this right cause i think i’m getting my self confused

All I can say is that you have over 75% of your answers is incorrect. The questions incorrect are numbers: 5, 7, 9, 10, 11, 12, 14, 15, 16, 17, and 20. What probably mess you up is probably the negative sign. When you see a negative sign, assume it is a subtraction sign. For example: -2+1 is the same as 1-2 which gets you -1. Same thing for (-3)+5 which is basically 5-3=2. Negative signs add a negative sign, -8+(-8) which is equivalent to -8-8 gets you -16. Negative signs while adding do not ever become a positive number unless it is a negative number subtract a negative number such as -8-(-8) which is the same as -8+8 = 0. If you cannot solve the problem, try to rearrange them due to associative property. It should get you the same answer. I hope this helps. The answers is right below here if you need to check afterwards.

Answers:

5) 4

7) -10

9) -13

10) -1

11) -1

12) -3

14) 4

15) 8

16) -16

17) -5

20) 4

You have a lot of these wrong. Hint:- when you have a + and - together it becomes a minus

For example 9 + (-5) = 9 - 5 = 4 ( problem 14)

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
