We can solve the system of equations to check the number of system of the solutions.
y=-6x+2 ...(1)
-12x-2y=-4 ...(2)
Substitute -6x+2 for y in equation (2). So,
-12x-2(-6x+2)=-4
-12x+12x-4=-4 (By distribution property).
-4=-4 (-12x and +12x has been cancel out).
Notice x has vanish from the above equation and we are left with -4=-4 which is correct.
So, the system has infinte number of solutions.
The solution is p = 10 and p = -2
To solve for both p's, you have to find two factors of -20 that when multiplied, equal -20, but when added equal -8 (2 and -10).Since the -20 is negative, one of the numbers has to be negative.
Now that you have the 2 numbers, you solve for "p".
P - 10 = 0. Add 10 to both sides, P = 10
P + 2 = 0. Subtract 2 on both sides. P= -2.
I hope this helps!

Answer:
Height = 30 mi.
Base = 120 mi.
Area = 3,600 mi^2.
Step-by-step explanation:
Let the height be x then the base = 4x.
The perimeter = 2*base + 2*height
= 2*4x + 2x
= 10x.
10x = 300
x = 30.
So the height is 30 mi and the base = 4*30 = 120 mi.
The area = height * base
= 30 * 120
= 3600 mi^2.
Answer:
Okay so basically your going to distribute the first equation where it says 4(2x+1) which gives you 8x+4.As you can see that is one of the answers on the right of it so then you go and answer the next problem 3(y+2) ect.If ya need help I can help you too?
