Answer:

D is the correct representation.

\frac{\frac{4x^2 + 2x}{x^{2}+x-2} }{ \frac{8x^2 +4x}{3x^2 +10x+8} } =  {\frac{(3x+4)}{2(x-1)}

Step-by-step explanation:

Here, the given equation is:

\frac{\frac{4x^2 + 2x}{x^{2}+x-2} }{ \frac{8x^2 +4x}{3x^2 +10x+8} }

here, numerator  = {\frac{4x^2 + 2x}{x^{2}+x-2} }

and denominator = \frac{8x^2 +4x}{3x^2 +10x+8}

Solving numerator and denominator separately, we get

NUMERATOR:

{\frac{4x^2 + 2x}{x^{2}+x-2} } \implies\frac{2x(2x +1)}{x^{2} + 2x-x-2 } \\\implies\frac{2x(2x +1)}{(x+2)(x-1) }

Denominator:

\frac{8x^2 +4x}{3x^2 +10x+8}  = \frac{4x(2x+1)}{3x^2 +6x+ 4x+8}\\ \implies \frac{4x(2x+1)}{3x(x+2)+ 4(x+2)}  =  \frac{4x(2x+1)}{(3x+4)(x+2)}

Hence, the transformed  fraction is:

\frac{\frac{2x(2x +1)}{(x+2)(x-1) }}{\frac{4x(2x+1)}{(3x+4)(x+2)}}  = {\frac{2x(2x +1)}{(x+2)(x-1) }} \times{\frac{(3x+4)(x+2)}{4x(2x+1)}

or, implied fraction is  {\frac{(3x+4)}{2(x-1)}

Hence, D is the correct representation.

Answer:

  A'(-4, -4), B'(6, -4), parallel

Step-by-step explanation:

Use the formula for interest P=750 r=7% Y=25 A=?
Over [174]

Answer:

2062.50

Step-by-step explanation:

Interest = (Principle x rate x time)/100

Amount = Principle + interest

Principle = 750

Rate = 7%

Time = 25 years

(750 x 7 x 25)/100

= 131250/100

=1312.50

Principle = 750

Interest = 1312.50

Amount = 750 + 1312.50

Amount = 2062.50

Trey drove 250 miles using 9 gallons of gas. At this rate, how many gallons of gas would he need to drive 275 miles?
GarryVolchara [31]

Answer:

10 gallons of gas.

Step-by-step explanation:

250/9 = how many miles 1 gallon of gas will take

250/9 = 27.78

1 gallon of gas = 27.78 miles

275/27.78 = 9.90 gallons

9.90 gallons round up to 10 gallons

Therefore, Trey would need 10 gallons of gas to drive 275 miles.

A box weighs 90 grams.<br>Write down, in terms of b, the weight of b boxes.​
Drupady [299]

Answer:

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

hope this helps
