Hamadi and aisha solve this problem in two different ways. carlos paid a total of $64 to rent a car. the rental company charges a one-time fee of $20, with an additional charge of $0.50 per mile driven. how many miles did carlos drive the rental car? use the drop-down menus to complete the sentences below. hamadi's and aisha's methods use operations to simplify the expressions in order. hamadi's method uses , but aisha's method does not.

we are given: one time fee to rent a car = $20.

additional charge per mile = $0.50 .

total rent paid by carlos = $64.

we can setup an expression for the given situation.

one time fee + charge per mile of * number of miles = total rent paid.

let us assume number of miles travelled by carlos = = x miles

so, we can setup an equation by using above expression we wrote.

20 + 0.50 * x = 64.

20 +0.50x = 64.

now, let us follow some steps to solve the equation we got.

20 is added on left side.

we always apply reverse operation in an equation to solve.

the reverse operation of addition is subtraction.

therefore, subtracting 20 from both sides, we get

20-20 +0.50x = 64-20   ( by subtraction property of equality)

now   we can see we have 0.50 in front of x. so, we need to get rid 0.50 by division property of equality.

dividing both sides by 0.50, we get

0.50x/0.50 = 44/0.50  

on simplification, we get

x=22.

therefore, carlos drove 22 miles the rental car.

the answer is: mark as brainlist.

hamadi's and aisha's methods "the same"   operations to simplify the expressions "the same"   order.

hamadi's method " a variable" , but aisha's method does not.

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
