Answer:

12 units

Step-by-step explanation:

B - A = (7, 8) - (-5, 8) = (7 -(-5), 8 -8) = (12, 0)

The distance is then ...

d = √(12² + 0²) = √12²

d = 12

_____

Of course, when you graph these points (actually or mentally), you can see that they are 12 units apart on the line y=8. You don't need to do any fancy calculation to discover the difference between -5 and 7.

Answer:

g =6/5 g=-5/2

Step-by-step explanation:

(5g − 6)(2g + 5) = 0

Using the zero product property

(5g − 6) =0 (2g + 5) = 0

5g-6+6 =0+6 2g+5-5=0-5

5g =6 2g =-5

5g/5 = 6/5 2g/2 =-5/2

g =6/5 g=-5/2

tatuchka [14]

Answer:

No, they aren't similar.

Step-by-step explanation:

<u><em>Let's take the proportionality of their sides to check whether they are similar or not:</em></u>

$\frac{10}{5} = \frac{12}{4}$

=> 2 ≠ 3

So, they are not similar.
