This is how I'd work it:

2(x-1)+3(x+1)=4(x+4)
     2x-2+3x+3=4x+16
              5x+1=4x+16
                    <u>x=15</u>

To check, substitute x into the original equation and solve: 

2(15-1)+3(15+1)=4(15+4)
                28+48=76
                      76=76

Consider triangle WXY... which statement about the angles is true?
Brrunno [24]

Answer:  The correct option is (A) Angle W is greater than angle Y.

Step-by-step explanation:  Given that the measures of the three sides of a triangle XYZ are as follows:

XY = 10 units,

WY = 14 units,

WX = 5 units.

We are to select the correct statements regarding the angles of ΔXYZ.

Writing the lengths of the sides in ascending order, we have

5

Since the angle opposite to a smaller side of a triangle is smaller, so from inequality (i), we get

WX

Option (A) is "Angle W is greater than angle Y".

This option is correct, because we have  ∠W > ∠Y.

Option (B) is "Angle Y is the largest angle".

This is incorrect because ∠X is the largest angle.

Option (C) is "Angle X is smaller than angle W"

This is incorrect because ∠X is the largest.

Option (D) is  "Angle W is the smallest angle".

This is incorrect because ∠Y is the smallest.

Thus, (A) is the correct option.
