Answer:

2x^{2}  + 6x - 4

Step-by-step explanation:

(3x^{2}  + x - 3) - (x^{2}  - 5x + 1) \\ 3x^{2}  + x - 3 - x^{2}  + 5x - 1 \\ combine\: like \: terms \\ 2x^{2}  + 6x - 4

Subtract each term of g(x) from each corresponding term of f(x)

3x^2 - x^2 = 2x^2

X—5x = x +5x = 6x

-3 -1 =-4

Now combine them to get final answer:

2x^2 + 6x -4

What is the length of BC , rounded to the nearest tenth?
Arte-miy333 [17]

Step 1

In the right triangle ADB

<u>Find the length of the segment AB</u>

Applying the Pythagorean Theorem

AB^{2} =AD^{2}+BD^{2}

we have

AD=5\ units\\BD=12\ units

substitute the values

AB^{2}=5^{2}+12^{2}

AB^{2}=169

AB=13\ units

Step 2

In the right triangle ADB

<u>Find the cosine of the angle BAD</u>

we know that

cos(BAD)=\frac{adjacent\ side }{hypotenuse}=\frac{AD}{AB}=\frac{5}{13}

Step 3

In the right triangle ABC

<u>Find the length of the segment AC</u>

we know that

cos(BAC)=cos (BAD)=\frac{5}{13}

cos(BAC)=\frac{adjacent\ side }{hypotenuse}=\frac{AB}{AC}

\frac{5}{13}=\frac{AB}{AC}

\frac{5}{13}=\frac{13}{AC}

solve for AC

AC=(13*13)/5=33.8\ units

Step 4

<u>Find the length of the segment DC</u>

we know that

DC=AC-AD

we have

AC=33.8\ units

AD=5\ units

substitute the values

DC=33.8\ units-5\ units

DC=28.8\ units

Step 5

<u>Find the length of the segment BC</u>

In the right triangle BDC

Applying the Pythagorean Theorem

BC^{2} =BD^{2}+DC^{2}

we have

BD=12\ units\\DC=28.8\ units

substitute the values

BC^{2}=12^{2}+28.8^{2}

BC^{2}=973.44

BC=31.2\ units

therefore

<u>the answer is</u>

BC=31.2\ units

Write equivalent expressions using distributive property. m(4+7)
yulyashka [42]

Hey there!

m(4 + 7)

= 1m(4 + 7)

DISTRIBUTE m WITHIN the PARENTHESES

= m(4) + m(7)

= 4(m) + 7(m)


= 4(1m) + 7(1m)


= 4m + 7m


COMBINE the LIKE TERMS

= 11m


Therefore, your answer is: 11m


Good luck on your assignment & enjoy your day!
