<u>Answer:</u>
D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11
<u>Step-by-step explanation:</u>
We are given the following two expressions:
and
Now if we look at the option D) 
and 
, we can observe that the earlier part in the given expression is just a simplification of 6x^2 - 8y^2 = 50.
and the later part is already the same.
Therefore, the correct answer option is D) 6x^2 - 8y^2 = 50
-6x^2 - 2y^2 = 11.
-12ab+7a power of 2 +a 11
the conversion is:
0.50 sen /g = 5 RM/kg
<h3>
How to change the units?</h3>
First, we know that
1sen = 0.01RM
Then we can change:
0.50 sen /g = 0.50*(0.01 RM) /g = 0.005 RM/g
Now we use the relation:
1g = 0.001kg
So we can rewrite:
0.005 RM/g = 0.005 RM/(0.001kg) = 5 RM/kg
So the conversion is:
0.50 sen /g = 5 RM/kg

Answer:
2±√13
Step-by-step explanation:
9/x=x-4
x² -4x - 9=0
x² -4x +4- 13=0
(x -2)²=13
x-2= ±√13
x= 2±√13
Answer:
B. m<B = 65°; m<C = 115°
Step-by-step explanation:
First find the value of x:
3n + 20 = 6n - 25 (opposite bangles if a parallelogram are equal)
Collect like terms
3n - 6n = -20 - 25
-3n = -45
Divide both sides by -3
n = 15
✔️Find angle B:
m<B = 3n + 20
Plug in the value of n
m<B = 3(15) + 20
m<B = 45 + 20
m<B = 65°
✔️Find angle C:
m<C = 180 - m<B (consecutive angles of a parallelogram are supplementary)
m<C = 180 - 65
m<C = 115°
