Answer:

Step-by-step explanation:

Answer: A is 88
Step-by-step explanation:
Sum of all angles is 180 degree.
Let the third interior angle be x.
38+50+x=180
88+x=180
x= 92
A and X are in linear pair.
A+X=180
A+92=180
A=88
The answer is D, because the others can be solved. A when factored is equal to -3, when B is factored it is equal to 3,-1, when C is factored it is 1,-4. D can be solved but you will only get irrational numbers which can't be used.
Answer:
12.25
Step-by-step explanation:
(1): "36.75" was replaced by "(3675/100)".
2 Simplify 147/4
3 147 /4 divided by 3
.....
49/4 which equal 12.25000
<span>A = 2ab + 2ac + 2bc
A = 2b(a + c) + 2ac
2b(a + c) = A - 2ac
b = (A - 2ac) / [2(a + c)]</span>
