Answer:

5x - 1

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), thus

f(x) + g(x)

= 3x - 2 + 2x + 1 ← collect like terms

= 5x - 1

Given: ABC is similar to XYC. If BY = 6, YC = 10, AX = 18, then XC = 10.8 5 30 48

Sidana [21]

Answer:

The correct option is 3. The length of XC is 30.

Step-by-step explanation:

It is given that triangle ABC and triangle XYC are similar.

According to the properties of similar triangles, then corresponding sides of similar triangles are congruent.

In triangle ABC and triangle XYC,

$\frac{AB}{XY}=\frac{BC}{YC}=\frac{AC}{XC}$

Let the length of XC be x.

From the below figure it is notices that

$AC=AX+XC=18+x$

$BC=BY+YC=6+10=16$

$\frac{16}{10}=\frac{18+x}{x}$

$16x=180+10x$

$6x=180$

$x=30$

Therefore correct option is 3. The length of XC is 30.

Hint: Find the value of x first, then subsitute the answer into 2x- 24.

Artemon [7]

Step-by-step explanation:

$\because \: \angle \: BCD = \angle \: BFG \\ (corresponding \: angles) \\ \therefore \: x + 26 \degree = 2x - 24\degree \\ \therefore \: x - 2x = - 26 \degree- 24\degree \\ \therefore \: - x = - 50\degree \\ \therefore \: x = 50\degree \\ \\ \therefore \: m \: \angle \: BFG = 2x - 24\degree \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 50\degree - 24\degree \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:= 100\degree - 24\degree \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:= 76\degree \\ Hence, \\ \huge \red{ \boxed{ \: m \: \angle \: BFG =76\degree }}$
