The Johnsons’ new swimming pool measures 3x^2-2x+1 ft in length and x+2 ft in width. What is the area of the new swimming pool,

Usimov [2.4K]

Answer:

$3x^3 + 4x^2 -3x + 2$

Step-by-step explanation:

The area of the swimming pool will be equal to $length * width$ .

We know that the length is $3x^2-2x+1$ and the width is $x+2$ .

Therefore we can substitute those into the equation:

$(3x^2-2x+1)(x+2)\\$

Then, we expand the brackets using a grid (attached).

After this, we collect like terms to find the final answer:

$3x^3+6x^2-2x^2-4x+x+2\\3x^3 + 4x^2 -3x + 2$

Our final answer is: $3x^3 + 4x^2 -3x + 2$

-.At a fair hamburgers sell for $3.00 each and hot dogs sell for $1.50 each. The equation 3x + 1.5y = 30 describes the number of

NikAS [45]

Answer:

Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)

The graph in the attached figure

Part b) See the procedure

Step-by-step explanation:

The questions are

Part a) Find the intercepts and graph the function

Part b) What does each intercept represent?

Part a) Find the intercepts and graph the function

Let

x-----> the number of hamburgers

y ----> the number of hot dogs

we have

$3x+1.5y=30$

Remember that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$3(0)+1.5y=30$

$1.5y=30$

$y=20\ hot\ dogs$

The y-intercept is the point (0,20)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$3x+1.5(0)=30$

$3x=30$

$x=10\ hamburgers$

The x-intercept is the point (10,0)

Plot the intercepts and graph the line

see the attached figure

Part b) What does each intercept represent?

The x-intercept is the number of hamburgers they can buy if they buy no hot dogs

The y-intercept is the number of hot dogs they can buy if they buy no hamburgers
