If NML ~ SRL find the value of x.

katen-ka-za [31]

Answer:

x = 5

Step-by-step explanation:

Since the triangles are similar, corrresponding sides are in proportion.

$\frac{NM}{SR} = \frac{ML}{RL} = \frac{NL}{SL}$

Using the equation formed by the second and third fraction above we get

$\frac{28}{24} = \frac{3x - 1}{x + 7}$

28(x + 7) = 24(3x - 1)

28x + 196 = 72x - 24

44x = 220

x = 5

Applying properties to write equivalent expressions for 2x+5y+5(2x+5y)

levacccp [35]

Solving expression $2x+5y+5(2x+5y)$ we get $12x+30y$

Step-by-step explanation:

We need to solve the expression:

$2x+5y+5(2x+5y)$

Solving:

Multiplying 5 with terms inside the bracket:

$2x+5y+5(2x+5y)\\=2x+5y+10x+25y\\Combining\,\,like\,\,terms:\\=2x+10x+5y+25y\\=12x+30y$

So, Solving expression $2x+5y+5(2x+5y)$ we get $12x+30y$
