Answer:
# = -2
Step-by-step explanation:
3 x # = -6
3 / -6 = -2
# = -2

Answer:
x = 0 or x = -2
Step-by-step explanation:
x^4+8x=0
Step 1: Factor left side of equation.
x(x+2)(x2−2x+4)=0
Step 2: Set factors equal to 0.
x=0 or x+2=0 or x2−2x+4=0
x=0 or x=−2
We will calculate this by using ratios and because these two triangles are similar, which is very important.
Explanation:
We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.
9 : 21 = 18 : x
x = (21*18)/9
x = 378/9
x = 42.
The correct answer is B. 42.
