Answer:
56
Step-by-step explanation:
Perimeter= 4S
Perimeter= 4(5)
Perimeter= 20
Perimeter 2= 2(L+W)
Perimeter 2= 2(11+7)
Perimeter 2= 22+14
Perimeter 2= 36
Total Perimeter= P1+P2
Total Perimeter= 20+36
Total Perimeter= 56
Hello from MrBillDoesMath!
Answer:
The first choice ( -12, 20)
Discussion:
Using matrix multiplication we find the equations:
1x + 1y = 8 (A)
2x + 3y = 36 (B)
Next, compute
2(A) - B =>
(2x + 2y) - (2x + 3y) = 2*8 - 36 =>
(2x - 2x) + ( 2y-3y) = 16 - 36 =>
-y = -20 =>
y = 20
Substituting this y value in (A) gives
x + 20 = 8 =>
x = 8 - 20 =>
x = -12
The answer is the first choice ( -12, 20)
Thank you,

Answer:
Step-by-step explanation:
im pretty sure it is 768/187.5 = about 4
because you are taking the highest number and putting it over the lowest number
I might be wrong in this one but I am certain to the right Is definitely -3. If I get it wrong can you tell me what I got wrong to improve from my mistakes.
Step-by-step explanation:
4x+ 5x - 5 +6 +4y^3- 2y^3- 5y^3
9x + 1 + 64y - 8y - 125y
9x + 1 - 69y
