What is -4 + (-6)? I need to show my work also

-10

Step-by-step explanation:

-4 + (-6)

-4 - 6

-10

if you didnt know, there is always an invisable 1 before the parentheses unless there is a number there. so think about it as -4 + 1(-6). then, -6 times 1 is still -6.

hope this helps!!!

just needed some points but try socratic

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.
