Answer:
15x - 2
Step-by-step explanation:
Since there is an addition sign in between the parentheses, just ignore the parentheses all together. You can't combine anything inside the parentheses anyways.
New expression:
12x + 5 + 3x - 7
Combine like terms.
12x + 3x = 15x 5 - 7 = -2
Answer:
15x - 2
Answer:a 2 − b 2 = ( a + b ) ( a − b ) where a = 6 a and b = 7 b . ( 6 a + 7 b ) ( 6 a − 7 b

Answer:
(x-7)(x+3) thats the answer for your question
Answer:
9. 6k + 5 and 2k - 1.
10. 5√2 .
Step-by-step explanation:
9. Area = 12k^2 + 4k - 5
Factoring:
12k^2 - 6k + 10k - 5
= 6k(2k - 1) + 5(2k - 1)
= (6k + 5)(2k - 1)
So the required lengths are 6k + 5 and 2k - 1.
10. The ratio of a leg to the hypotenuse is 1: √2 so if the hypotenus = 10 the length of a leg is 10 / √2
= 10 √2 / 2
= 5√2 .
I think the answer is 1 over 2 (0.5), thats if i understand what you’re saying
