Answer:
The answer is B
Step-by-step explanation:
x/-y is equivalent to -(x/y)
20 + 8x = 32
- 20
8x = 12
-- --
8 8
x = 3/2= 1 1/2
Answer:
w = 2, EF = 30 , FG = 42
Explanation:
We have EF = 5w + 20 and FG = 7w + 28
Since these points E, F and G are col-linear points we have.
EG = EF + FG
And given that EG = 72
So, EF+EG = 72
5w + 20 + 7w + 28 = 72
12w + 48 = 72
12 w = 24
w = 2
So EF = 5w + 20 = 5x2 + 20 = 30
FG = 7w + 28 = 7x2 + 28 = 42
By the quadratic formula,
Then
Multiply numerator and denominator by the denominator's conjugate:
