Answer:

A) x = 12

B) = 154

Step-by-step explanation:

RVT is a straight line so it must have an angle of 180º. If we take the 26º from ST we know that RS is equal to 154º

So we should set the equation (15x-26) = 154

We should always keep the equation balanced so to do this we're going to add 26 to both sides to get x by itself.

Your equation should now look like this. 15x = 180

Then divide both sides by 15 to get x = 12

We know that UR is also 26º because RS is 154º That makes RU congruent to ST and RS congruent to UT

f(x) = 3x2 - 2x g(x) = x + 4 When finding f(x) · g(x), what could the first step look like? A) 3x2 + 12x2 - 2x2 - 8x B) 3x2 + 7x
Anna71 [15]

(3x^2 - 2x)(x + 4)

<em><u>First step would be: distributive property.</u></em>

3x^3 + 12x^2 - 2x^2 - 8x

<em><u>Combine like terms.</u></em>

3x^3 + 10x^2 - 8x is the simplified form of the functions multiplied.

Your answer is D.

Answer:

<h2><em><u>0</u></em></h2>

Step-by-step explanation:

<em><u>The rational number 0 is the additive identity for rational numbers</u></em><em><u>.</u></em>

<em><u>As</u></em><em><u>,</u></em>

<em><u>If</u></em><em><u> </u></em><em><u>we</u></em><em><u> </u></em><em><u>add</u></em><em><u> </u></em><em><u>any</u></em><em><u> </u></em><em><u>rational</u></em><em><u> </u></em><em><u>number</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>zero</u></em><em><u> </u></em><em><u>we</u></em><em><u> </u></em><em><u>get</u></em><em><u> </u></em><em><u>that</u></em><em><u> </u></em><em><u>number</u></em><em><u> </u></em><em><u>itself</u></em><em><u>.</u></em>

<em>E.g</em><em>.</em>

0 +  \frac{1}{2}  =  \frac{1}{2}

and

0 + ( -  \frac{5}{6} ) = ( -  \frac{5}{6} )

Multiply. Write your answer as a fraction in simplest form.<br> 5/2*3/10
kherson [118]
(5/2)(3/10)=(5*3)/(2*10)=15/20=3/4

Or

(5/2)(3/10)= (5)(1/2)(3)(1/10)=(5)(3)(1/2)(1/10) =(5*3)/(2*10)=15/20=3/4

Or

(5/2)(3/10)=(5)(0.5)(3)(0.1)=(2.5)(3)(0.1)=(7.5)(0.1)=.75=3/4

All of these work, but the first one is simplest
