Step-by-step explanation:

15x+3x+19= -17 please help me find this answer

15x+3x+19= -17

18x + 19 = -17

18x = -19 - 17

18x = -36

x = -36 : 18

x = -2

---------------

check

15(-2)+3(-2)+19=-17

-30 - 6 + 19 = -17

-17=-17

the answer is good

Solve for x. 50 = x^2 Show your work.

Tanzania [10]

50 = x^2

To isolate x you need to do the opposite of an exponent, which would be square root.

$\sqrt{50} = x Next solve what the square root of 50 is[tex]5\sqrt{2}$ = x

That is the exact form, in other words your answer, if teacher is looking for a decimal, it would be

7.07 = x

Expand each expression

matrenka [14]

Answer:

Option B - $\ln(\frac{4y^5}{x^2})=\ln 4+5\ln y-2\ln x$

Step-by-step explanation:

Given : Expression $\ln(\frac{4y^5}{x^2})$

To find : Expand each expression ?

Solution :

Using logarithmic properties,

$\ln (\frac{A}{B})=\frac{\ln A}{\ln B}=\ln A-\ln B$

and $\ln (AB)=\ln A+\ln B$

Here, A=4y^5 and B=x^2

$\ln(\frac{4y^5}{x^2})=\frac{\ln 4y^5}{\ln x^2}$

$\ln(\frac{4y^5}{x^2})=\ln 4y^5-\ln x^2$

$\ln(\frac{4y^5}{x^2})=\ln 4+\ln y^5-\ln x^2$

Using logarithmic property, $\logx^a=a\log x$

$\ln(\frac{4y^5}{x^2})=\ln 4+5\ln y-2\ln x$

Therefore, option B is correct.

Find the area of the triange below<br><br>units given are cm, cm^2, cm^3

notsponge [240]

Answer:

$A=150\ cm^2$

Step-by-step explanation:

The Hypotenuse of triangle, H = 25 cm

Base = 15 cm

Height = 20 cm

We need to find the area of the triangle. The area of a right-angled triangle is given by :

$A=\dfrac{1}{2}\times b\times h\\\\A=\dfrac{1}{2}\times 15\times 20\\A=150\ cm^2$

So, the area of the triangle is equal to $150\ cm^2$ .
