Please help me with this problem , and please please show your work , I’ll give you brainlist

Step-by-step explanation:

x+(x+2)+(6x+10)= 180⁰(sum of angles in a triangle)

Open the brackets by +1

x+x+2+6x+10. =. 180⁰

2x+6x+10+2. =. 180⁰

8x+12. =. 180⁰

8x. =. 180⁰-12⁰

8x. =. 168

x. =. 168/8

x. =. 21

x+2=2+21=23

6x+10=6×21+10=126+10=136

A+B+C=180⁰

21⁰+23⁰+136⁰=180⁰

180⁰ =180⁰

PLEASE MARK BRAINLIEST.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

1st part is 64,000,000

2nd part 500,000
