WORTH 15 POINTS PLEASE ANSWER ASAP!! MY YOUNGER BROTHER NEEDS HELP ON THIS!!!!<br> ∧ω∧
xxTIMURxx [149]

Answer:

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Step-by-step explanation:

Given:

Consider a rectangle ABCD as shown in the figure below where,

Area (ABCD) = 635 × 7 = 4445

Therefore length and width of a rectangle will be

LENGTH =635 = AB

WIDTH  = 7 = AD

To Find:

AE =?

EF = ?

FB = ?

Ar(EFGH)=?

Ar(ABCD) =?

Solution:

We know that area of the rectangle is given by

\textrm{Area of rectangle}= LENGTH\times WIDTH

\textrm{Area of rectangle ABCD}= 635\times 7=4445\ unit^{2}

Substituting the values we get

\textrm{Area of rectangle AEHD}= AE\times 7\\\\4200=AE\times 7\\\therefore AE=\dfrac{4200}{7}=600

Similarly for area rectangle FBCG,

\textrm{Area of rectangle FBCG}= FB\times 7\\\\35=FB\times 7\\\therefore FB=\dfrac{35}{7}=5

Now we have

AB = 635,

AE + EF + FB = 635\\\\600+EF+5=635\\\\EF=635 -605=30\\\therefore EF = 30

Similarly for area rectangle EFGH,

\textrm{Area of rectangle EFGH}= EF\times 7\\\\=30\times 7=210\ isunit^{2}

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Subtract.<br>(4x^2 + 8x - 2) - (2x^2 - 4x + 3)<br>Enter your answer, in standard form.​
vovikov84 [41]

Answer:

\large\boxed{(4x^2 + 8x - 2) - (2x^2 - 4x + 3)=2x^2+12x-5}

Step-by-step explanation:

(4x^2 + 8x - 2) - (2x^2 - 4x + 3)\\\\=4x^2 + 8x - 2 -2x^2 -(- 4x)- 3\\\\=4x^2+8x-2-2x^2+4x-3\qquad\text{combine like terms}\\\\=(4x^2-2x^2)+(8x+4x)+(-2-3)\\\\=2x^2+12x-5
