Answer:
The numbers are 6 and 14
Step-by-step explanation:
Let the two numbers be x and y
x-y = 8
x+y = 20
Add the two equations
x-y = 8
x+y = 20
-----------------
2x = 28
Divide by 2
2x/2 = 28/2
x = 14
Subtract the two equations
x-y = 8
-x-y = -20
-----------------
-2y = -12
Divide by -2
-2y/-2 = -12/-2
y = 6
The numbers are 6 and 14
I believe the answer is:
A. 8/9 n-11/3
Answer: Isolate the variable by dividing each side by factors that don't contain the variable.
k = −1
Since the triangle is cut in half, I’m guessing it’s 22.5
X^2 - 5x - 14 = 0
what multiplies to negative 14 and adds to negative 5? -7 and positive 2.
(x - 7) (x + 2) = 0
Lesser x = -2
Greater x = 7
