Answer:

check 2nd and last box. :))

Step-by-step explanation:

Ok, so I would work out the Area, then rule out a few of these options.

First of all, if you look closely, you can see that instead of an l(x), it's an l(w), which means that what l(w) equals, is a product of whatever l(x) is with w serving as its x (if that makes sense lol). so, we need to divide by w to figure out what l(x) is.

<u>3x³+2x²-4x+5</u>  <u>(3x³+5)+(2x²-4)</u> <u>(3x³+5)+2(x+2)(x-2)</u><difference of two squares

      x+2         ⇒      x+2          ⇒         x+2                  so then the (x+2)'s cancel

and you're left with 3x³+5+2x-4 ⇒ 3x³+2x+1 which is l(x). Now you're ready to see what A(x) equals.

x(3x³+2x+1)+2(3x³+2x+1) =

[(3x^4)+2x²+x]+(6x³+4x+2) =

(3x^4)+6x³+2x²+5x+2=A(x)

So now you can rule out the answers. <u>Number one</u> can be done mentally, and it's <u>not correct</u>. <em><u>Number 2 is definitely true</u></em>. Number three we need to work out.

<u>(3x^4)+6x³+2x²+5x+2</u>     <u>[(3x^4)+6x³]</u> (the rest doesn't matter)⇒ <u>3x³</u><u>(x+2)</u>

             x+2                ⇒                                                                    x+2

So then you're left with 3x³+2x²+5x+2 which is<em> not</em> equal to l(x), so the third option is false and ruled out. The <u>fourth one</u> you can just look at A(x) and conclude <u>it's false</u>, and the <u>third one is very obviously true</u>.

Barry Beach was convicted of murder in 1983 and sentenced to life in prison without parole. In 2015, Governor Bullock commuted B
maria [59]

Answer:

The correct answer to the following question will be Option 1 (All Montana residents).

Step-by-step explanation:

  • Barry Beach told journalists managed to gather next to the front main entrance of Montana federal penitentiary across lunchtime that perhaps the point in time seemed to be 'surreal.'
  • A news broadcast in Bozeman was desperately trying to find out how and why individuals in Montana perceive and say about the official launch of Beach. It certainly indicates 'All Montana Residents' seems to be the group of people of benefit after that.

Other choices aren't linked to just the scenario in question. Option 1 seems to be the perfect solution.

Answer:

  1. 2x
  2. 2
  3. 128x +640

Step-by-step explanation:

1.

  \displaystyle\frac{8x^2-4x}{4x-2}=\frac{4x(2x-1)}{2(2x-1)}=\boxed{2x}

__

2.

  \displaystyle\frac{8x-4}{x+3}-\frac{12x-20}{2x+6}=\frac{8x-4}{x+3}-\frac{4(3x-5)}{2(x+3)}=\frac{8x-4-2(3x-5)}{x+3}\\\\=\frac{8x-4-6x+10}{x+3}=\frac{2x+6}{x+3}=\frac{2(x+3)}{x+3}=\boxed{2}

__

3.

  \displaystyle\frac{(2x+10)^7}{(x+5)^6}=\frac{(2(x+5))^7}{(x+5)^6}=2^7(x+5)^{7-6}=128(x+5)\\\\=\boxed{128x+640}

Please help it’s due tonight. Your help will be greatly appreciated.There is also a graph. WILL PUT YOU AS BRAINLY!!!!!!
chubhunter [2.5K]

Answer: see below

Step-by-step explanation:

The shape is a trapezoid

Base 1 (BH) is 10

Base 2 (QA) is 14

Height is 5

Area

A=\frac{base_{1} +base_{2} }{2} h

A=\frac{10+14}{2} *5\\A=12*5\\A=60

Find distance between QB and HA

D=\sqrt{(x_{2} -x_{1}) ^{2}+(y_{2}-y_{1})  ^{2}

Q( -4,4)  B (-2,9)

D=\sqrt{(-2--4)^{2}+(9-4)^{2}  } \\D=\sqrt{2^{2} +5^{2} } \\D=\sqrt{29}

Perimeter

P=10+14+2\sqrt{29} \\P=24 +2\sqrt{29} \\P= 24+10.77\\P=34.77

Jay spent ten more than three times the number of hours on his science fair project than jamie spent on her project jay spent 43
Aliun [14]
Why did both of their names have to start with the same letter

x=jay hours
y=jamie huours

x=10+3y
x=43


so
43=10+3y
minus 10
33=3y
divide 3
11=y

jamies spent 11 hours
