What is 3/4(x2+4x+6)=13x-2

maxonik [38]

Answer:

$x_1=12.65\\\\x_2=0.685$

Step-by-step explanation:

$\frac{3}{4}(x^2+4x+6)=(13x-2)\\\\Multiply\ both\ sides\ by\ 4.\\\\3(x^2+4x+6)=4(13x-2)\\\\3x^2+12x+18=52x-8\\\\3x^2+12x+18-(52x-8)=0\\\\3x^2+12x-52x+18+8=0\\\\3x^2-40x+26=0$

Roots of Polynomial:

$Roots\ are\ polynomial\ ax^2+bx+c=0\\\\x=\frac{-b\pm \sqrt{(b^2-4ac)}}{2a}$

$Here\ a=3,\ b-40,\ c=26\\\\x=\frac{-(-40)\pm \sqrt{(-40)^2-4\times 3\times 26}}{2\times 3}\\\\x=\frac{40\pm\sqrt{1288}}{6}\\\\x_1=\frac{40+\sqrt{1288}}{6}\approx 12.65\\\\x_2=\frac{40-\sqrt{1288}}{6}\approx 0.685$

Rachel and four friends were going to the movies. Each ticket cost $11 and then they bought 2 popcorns at $3.75 each, and they e

Anastasy [175]

Answer:

Total amount spent $=\$73.5$

If they decide to split the bill, amount paid by each of the person $=\$15.25$

Step-by-step explanation:

Cost of each movie ticket = $11

Cost of 5 tickets = 5(11)= 55

Cost of each packet of popcorns = $3.75

Cost of two packets of popcorns = $2(3.75) = $7.5

Cost of each soda = $2.75

Cost of five sodas = $5(2.75) = $13.75

Total number of persons (Rachel and four friends) = 5

Total amount spent $=11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25$

If they decide to split the bill, amount paid by each of the person = $\frac{76.25}{5}=\$15.25$

You want to ship textbooks from Florida. The textbooks are $60 each plus $150 shipping. Let x represent the number of textbooks

sertanlavr [38]

I am assuming the problem is asking you to find an equation repersenting the situation.

In this case, realize that 150 will be a constant, and 60 will be attached to the $x$ variable, since the price of the textbooks changes based on how many textbooks there are.

Thus, the equation is:

$60x + 150 = y$

Our answer is 60x + 150 = y.
