Answer:
1, because you can subtract both equations to eliminate y , and you will be left with only x.
Step-by-step explanation:
Answer:
21x + 12
Step-by-step explanation:
Distribute
3(7x) = 21x 3(4) = 12
21x + 12
So that’s the answer cuz like terms cannot b combined with numbers
Answer:
500.0000cm³
Step-by-step explanation:
Answer:
The solutions are 1 , -6
Step-by-step explanation:
∵ (x + 2)(x + 3) = 12
∴ x² + 3x + 2x + 6 - 12 = 0
∴ x² + 5x - 6 = 0
∴ (x - 1)(x + 6) = 0
∴ x - 1 = 0 ⇒ ∴ x = 1
∴ x + 6 = 0 ⇒ x = -6
Refer to the image that I attached to my answer.
According to the graphing calculator, the two equations have two points of intersections (the points where the different colored lines cross).
Happy Studying~
