Step-by-step explanation:

10 is the amount that you want to multiply x with, and then add the 8 that it grew in birth

y=10x+8

2x²y - 4xy²

Substituting the value of x & y,

= 2(- 1)² × 1 - 4(- 1) × 1²

= 2 × 1 × 1 + 4 × 1

= 2 + 4

= 6

Hence, The value of the expression is 6.

Buying 10 cans for $5.80 is the best deal.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the question

We have

Cost of eight cans is $4.88

⇒ cost of one can = [tex]\frac{4.88}{8}[/tex] = $0.61

Cost of 10 cans is $5.80

⇒ cost of one can = [tex]\frac{5.80}{10}[/tex] =$0.58

Cost of 3 cans is $7.20

⇒ cost of one can = [tex]\frac{7.20}{3}[/tex] = $2.4

Hence, buying 10 cans for $5.80 is the best deal.

Step-by-step explanation:

The length of the rectangle is x + 9 whose width is gives as 2x.

To find the length of the rectangle, we need to express it in terms of the width.

Given:

width of the rectangle is 2x.

The formula for the area of a rectangle is

A = length × width.

As, the polynomial function for the area:

[tex]A(x) = 2x^2 + 18x[/tex]

So, set up the equation:

[tex]2x^2 + 18x =[/tex] [tex]{\text} width x length[/tex]

Substituting the given width = 2x in above equation gives

[tex]2x^2 + 18x = 2x * length[/tex]

Dividing both sides of the equation by 2x:

x + 9 = length

Therefore, the length of the rectangle is x + 9.

Answer:

h(x) = 2 × 3ˣ - 3²ˣ

Step-by-step explanation:

Given:

[tex]f(x) = 3^x[/tex]

[tex]g(x) = 3^{2x} - 3^x[/tex]

[tex]h(x) = f(x) - g(x)[/tex]

Then:

[tex]h(x) = 3^x - (3^{2x} - 3^x)\\h(x) = 3^x - 3^{2x} + 3^x\\h(x) = 2 \times 3^x - 3^{2x}[/tex]
