Answer:
B. Mitochondria
Step-by-step explanation:
Answer:
C. Infinite solutions
Step-by-step explanation:
I'll use the equal value method and make the second equation equal 6 instead of 18, so I have to divide the entire equation by 3
(6x+15y=18)/3 = 2x +5y = 6
The second equation is the same thing as the first one, meaning no matter what value they will equal the same thing, also meaning there are infinite solutions
Answer:
x^2 + 11 x + 28
Step-by-step explanation:
Expand the following:
(x + 4) (x + 7)
(x + 4) (x + 7) = (x) (x) + (x) (7) + (4) (x) + (4) (7):
x x + 7 x + 4 x + 4 7
x x = x^2:
x^2 + 7 x + 4 x + 4 7
4×7 = 28:
x^2 + 7 x + 4 x + 28
7 x + 4 x = 11 x:
Answer: x^2 + 11 x + 28
