∆LMN ∼ ∆PON. What is the value of x? Select one: a. 28 1/3 b. 36 c. 20 d. 25

yawa3891 [41]

Answer:

Option B. 36

Step-by-step explanation:

From the figure attached,

ΔLMN ~ ΔPON

Therefore, corresponding sides of these similar triangles will be in the same ratio.

$\frac{LM}{OP}=\frac{MN}{ON}=\frac{LN}{PN}$

$\frac{LM}{OP}=\frac{MN}{ON}$

$\frac{42}{14}=\frac{x}{12}$

x = $\frac{42\times 12}{14}$

x = 36

Therefore, measure of side MN = x = 36 units

Option B. will be answer.

Make for me number 21 thx

xz_007 [3.2K]

Method One

You could divide by 5 right away.

20/5 = - 3 + x

4 = - 3 + x Add 3 to both sides.

4 + 3 = x

x = 7

Method Two.

You could remove the brackets. This is slightly longer, but some questions can only be solved that way.

20 = 5(-3) + 5x

20 = -15 + 5x Add 15 to both sides

20 + 15 = 5x

35 = 5x Divide by 5

35/5 = x

7 = x

Help!!<br> Giving brainliest!!

Elanso [62]

$\dfrac{3}{5} (30x - 15) = 72$

$18x - 9 = 72$

$18x = 81$

$x = 4.5$

Answer: All that you checked are right, except the last one, x = 4.5 as well.

Simplify the expression (x^25)^-6/(x^-3)^48

borishaifa [10]

Answer:

Step-by-step explanation:

$Use\\\\(a^n)^m=a^{nm}\\\\\dfrac{a^n}{a^m}=a^{n-m}\\------------------\\\\\dfrac{(x^{25})^{-6}}{(x^{-3})^{48}}=\dfrac{x^{(25)(-6)}}{x^{(-3)(48)}}=\dfrac{x^{-150}}{x^{-144}}=x^{-150-(-144)}=x^{-150+144}=x^{-6}$
