I really need help with this one

Mathematics
1 answer:
Novay_Z [31]3 years ago
3 0

Answer:

28

Step-by-step explanation:

Since B is the midpoint of AC, that means AB = BC. That means 3x+4 = 5x-6. We can now set up an equation to solve for x:

3x+4 = 5x-6

3x+10 = 5x

10 = 2x

x = 5

Now that we know what x is, we can just plug x into the expression of AB and multiply it by 2:

(3*(5)+4)*2

=(15+4)*2

=19*2

=28

(side note: we could have plugged x into the expression of BC as well, but in this case plugging it into AB tends to be easier to solve)

Therefore, the length of AC is 28.

In the expression -5g12 whIn the expression -5g12 which part is the coefficient?ich part is the base?
kiruha [24]

Answer:

The coefficient is -5, and the base is 12.

Step-by-step explanation:

The coefficient is the number that the variable is being multiplied by in an expression, so -5 would be the coefficient in the expression -5g_{12}. The base would be the little subscript number that is next to the variable, so the base in the expression -5g_{12} is 12.
