Mathematics
1 answer:
Allisa [31]3 years ago
8 0

Answer:

A) 3a = 180°

B) a+ 55° + 36° = 180°

C) x + y + z = 180°

Step-by-step explanation:

The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )

The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.

The terms don't have to be similar, for instance the B option,

a+ 55° + 36° = 180°

since you could find the value of a.

The same thing goes for C.

(Extra)

It is not D since x is multiplied with 3, not giving the sum.

It is not E since all the 3 terms are multiplied, not giving the sum.

You are asked to tutor a friend in algebra with adding and subtracting trinomials. Create an example of how to add two trinomial
vesna_86 [32]
Addign trinomials (2x+4xy+8z)+(8x+5xy+23z) all you have to do is combine the like terms 2x and 8x= 10x, 4xy+5xy=9xy, and 8z+23z=31z. so the simplified answer to adding the trinomials would be 10x+9xy+31z. 

Subtacting trinomials (4x+9y+3) - (-1+3x-2y) . 
When doing subtracting you still combine like terms but this time you change the sign before every term. If that is confusing, just pretend there is a negative 1 infront of parenthases and multiply that before you subtracts the two trinomials. so...
4x - 3x= x, 9y+2y=11y and 3+1=4. so simplified answer of the subtraction would be x+11y+4 

I hope this helped :) Good luck !
