Step-by-step explanation:
Given
x² - 9x + 20 = 0
x² - ( 4 + 5) x + 20 = 0
x² - 4x - 5x + 20 = 0
x ( x - 4 ) - 5 (x - 4 ) = 0
(x - 4 ) ( x - 5 ) = 0
Either
x - 4 =0
x = 4
or
x - 5 =0
x = 5
x = 4 and 5
Hope it will help :)

The answer is 1/6 x (25/3m^2n^2-1)
Answer:
no solution.
Step-by-step explanation:
1. 7x + 3 = 7x - 4 Subtract 7x on both sides
2. 3 = -4
Three does not equal to negative four so, it has no solutions
His next step would be:
(8 x 10) + (8 x 7)
Why?
Because when using the distributive property, you distribute the number outside of the parentheses to the numbers inside the parentheses, and in this case, we are multiplying so you will multiply 8 by both 10, and 7.
Hope this helps!

My answer I came up with is 12. I said 12 because if you start with 10 strawberries you would add 10 six times and get 60. So that means that you would need to multiple 2 by 6 as well. If this isn’t right I’m soooooo sorry
