Is 5f + 4 -3f -2 = 2f -2

Naya [18.7K]

Combine like terms on left side:

(5f-3f)+(4-2)=2f-2

2f+2=2f-2 subtract 2 from both sides

2f=2f-4 subtract 2f from both sides

0=-4

Since the above in not true,

5f+4-3f-2 does not equal 2f-2 for any value of f....

The value of x is 8.

Solution:

Given $\triangle V D G \sim \triangle V N Q$ .

DG = 60, NQ = 48, DN = 15, NV = x + 4

<u>To find the value of x:</u>

<em>Property of similar triangle:</em>

If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.

$$\Rightarrow\frac{DG}{NQ} =\frac{DN}{NV}$

$$\Rightarrow\frac{60}{48} =\frac{15}{x+4}$

Do cross multiplication.

$$\Rightarrow60(x+4)=15\times48$

$$\Rightarrow60x+240=720$

Subtract 240 from both side of the equation.

$$\Rightarrow60x+240-240=720-240$

$$\Rightarrow60x=480$

Divide by 60 on both sides of the equation.

$$\Rightarrow\frac{60x}{60} =\frac{480}{60}$

$$\Rightarrow x=8$

Hence the value of x is 8.
