Answer:
(3 x + 5) (x + 5)
Step-by-step explanation:
Factor the following:
3 x^2 + 20 x + 25
Hint: | Factor 3 x^2 + 20 x + 25 by finding factors of 3×25 whose sum is 20.
Factor the quadratic 3 x^2 + 20 x + 25. The coefficient of x^2 is 3 and the constant term is 25. The product of 3 and 25 is 75. The factors of 75 which sum to 20 are 5 and 15. So 3 x^2 + 20 x + 25 = 3 x^2 + 15 x + 5 x + 25 = 5 (3 x + 5) + x (3 x + 5):
5 (3 x + 5) + x (3 x + 5)
Hint: | Factor common terms from 5 (3 x + 5) + x (3 x + 5).
Factor 3 x + 5 from 5 (3 x + 5) + x (3 x + 5):
Answer: (3 x + 5) (x + 5)
Answer:
The first graph to the left
Step-by-step explanation:
The second graph is parallel lines so they will never intersect
The third graph one line so they are infinite solutions
The first graph will intersect at one point
The solution to the equation is x = 20.
<u>Step-by-step explanation</u>:
The equation is 2( x – 5) = 9 – 3 x + 6 + 8 + 3 x + 7
2x - 10 = 30
2x = 30+10
2x = 40
x = 40/2
x = 20
Your answer is B 1,536 in. good luck
