Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 to both sides
-6 (+10) = n/2 - 10 (+10)
10 - 6 = n/2
4 = n/2
Next, isolate the n. Multiply 2 to both sides
4(2) = n/2(2)
n = 4(2)
n = 8
8 is your answer

Answer:
Step-by-step explanation: The surface area is the area of the rectangular base (length width) plus the areas of each of the four triangular faces. The area of a triangle is 1/2 base height so all that remains is to find the height of each of the triangular faces.
Answer:
A: 38º
Step-by-step explanation:
Triangle JKL is an isosceles triangle as JK=KL:
- That means ∠J=∠L=71º
- The sum of a triangle's interior angles is 180º, so ∠K=180º-∠J-∠L. We know ∠J=∠L=71º, so ∠K=180º-71º-71º=38
