Answer:
(10 x 10 18 times)(10 x 10 23 times) 
just as a note: when you multiply numbers with exponents and they both have the same base, all you have to do is add the exponents.
Ex: 
20 and 28 can be divided by 4, so just take the 4 out so the answer should be 4(5x - 7)
It is 348000 because if its 5 or above it rounds up and 4 or below rounds down so the 5 rounds the 7 to an 8

Answer:
(-5, 2) and (2, 6)
Step-by-step explanation:
Use the substitution method. We know that y = 3x and y = x^2 - 10, so we can set them equal to one another.
3x = x^2 - 10
x^2 - 3x - 10 = 0
Use the quadratic equation to solve for x.
x = - 5, 2
Now solve for y using these two values of x by substituting it back into the equations.
y = - 15, 6
In coordinate form, (-5, 2) and (2, 6)
