Question
a(7x+3)=b+14x what is the value of a and b

I hope this helps? I am so so sorry if it does'nt

Step-by-step explanation:

a(7x+3)=b+14x

Step 1: Factor out variable a.

a(7x+3)=b+14x

Step 2: Divide both sides by 7x+3.

a(7x+3)

7x+3

=

b+14x

7x+3

a=

b+14x

7x+3

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
