x + 16 = 3x
x = 8 (football cards)

A garden is in the shape of a rectangle and has a perimeter of 58 yards. The length of the garden is 5 more than twice the width. Find the dimensions of the garden.

Answers

Let the width be w
Length= 2w+5
Perimeter= 2(length+width)
58=2(2w+w+5)
58=2(3w+5)
3w+5=29
3w=24
Width=8yards
Length=2(8)+5
=21yards

p= sum of the sides = 2l+2wopposite sides are the samex=width2x+5= length2x+ 2(2x+5)=58remove( )2x+ 4x+10=58combine like terms6x+10= 58subtract 10 from both sides6x=48divide by 6x=8 width2 x 8+5= 21 lengthhope this helps

Which is bigger 20% of 300 or 1/4 of 200

Answers

to find 20% of 300, multiply .2 x 300 = 60
60 is 20% of 300

1/4 = 25%
to find 25% of 200, multiply .25 x 200 = 50
50 is 1/4 of 200

20% of 300 is more than 1/4 of 200

(20/100) *300 = (2/1)*30= 60(1/4) * 200= 200/4 = 50

Construct a polynomial function with the following properties: fifth degree, −2 is a zero of multiplicity 2, 4 is the only other zero

Answers

5th degree means highest power is 5 total

zeroes/roots are
(x-r)
so -2 is a root
(x-(-2))
(x+2) is a root
multiplicity 2 means it happens 2 times ie
(x+2)^2
e
4 is the only other zero
(x-4)

so now we have
(x-4)(x+2)^2
but that is only 3rd degreed
I could add 2 more degrees that are complex roots and therefor won't be graphed on the plane since they are complex so
find a 2nd degree polynomial that has only complex roots
a complex 2nd degree polynomial
x^2+x+10

ok so this is the function
f(x)=(x-4)(x+2)^2(x^2+x+10)

Really need help lol...Kristin lives in Alaska. She drives a car with a 12-gallon fuel tank. When Kristin fills her empty gas tank in Alaska, she has to pay a federal gasolinetax of $.18 (or 18 cents) per gallon, plus a state gas tax of 8 cents ($.08) per gallon. Her taxes paid for a gallon of gas equal 26 cents. You can calculate the percentage of a purchase that goes to taxes by dividing the tax amount by the total sale price. If Kristin buys gas at $3.69 per gallon, which includes all taxes, what percentage of the price is the state tax? What percentage is the federal tax?
