Answer:
-12 , -6
Step-by-step explanation:
- 7 - 5 = - 12
- 2 - 4 = - 6
Euler's formula for a polyhedron is given by:

Make E, the subject of the formula:

Put F = 20, V = 12, to obtain E,

Therefore, there are 30 edges
Think the 4 less than but not equal to as a equal sign
step 1. isolate the variable ( variable must stand alone)
step 2. subtract 12n -12n=0
step 3. since you subtract 12n from the left you must do the same to the right.
step 4. 13n - 12n =1n
step 5. the equation should look like this -4 less than but not equal to 1n
step 6. isolate the variable n
step 6. divide 1n/1 on the right and on the left -4/1 it equals -4
so, n is -4
Answer:
A, 3/4(4/3)x=-6(4/3)
Step-by-step explanation:
Multiplying each side of the equation by 4/3 isolates x and solves the equation in one step.
