Given the function below, evaluate h(2) for x = -2
h(x) = -4x2 + x +1

Answer:

-3x²+18x-27

Step-by-step explanation:

Given :

-3X²+18x

perfect square : (a+b)²=a² + 2ab + b²

[tex]\frac{-3x^{2} }{-3} +\frac{18x}{-3} ... something else[/tex] divide by -3 to have just a² type

x² -6x ...and something

compare with the perfect squere formula and we know a² is x² , a is x, so second term is 2xb and is -6x so b= -3

x²-6x+9 = (x-3)²

if you reverse and multiply by (-3) we have

-3x²+18x-27

Answer:

The perimeter is equal to 240.

Step-by-step explanation:

Since  the shape is a regular polygon, the sides are equal to each other, so those two equations are equal to each other.

So, to solve for x, then to find perimeter, we need to set the equations equal to each other.

5x + 10 = 7x + 4

Subtract 5x  and -4 from both sides.

6 = 2x

Divide each side by 2.

3 = x

Now, we plug it into one of the equations and multiply by 6 (6 sides in the regular polygon).

5( 6 + 2 )

40

40 * 6 = 240

The perimeter is equal to 240.

Perimeter of the regular polygon is 150 unit

Given:

Equal first side of regular polygon = 7x + 4

Equal second side of regular polygon = 5(x + 2)

Find:

Perimeter of the regular polygon

Computation:

We know that side of regular polygon are equal

7x + 4 = 5(x + 2)

7x + 4 = 5x + 10

7x - 5x = 10 - 4

2x = 6

x = 3

So,

Side of regular polygon = 7x + 4

Side of regular polygon = 7(3) + 4

Side of regular polygon = 25 unit

We know that given polygon is hexagon

Perimeter of hexagon = 6(a)

Perimeter of hexagon = 6(25)

Perimeter of hexagon = 150 unit

Combination and permutation are two different ways of grouping elements of a set into subsets in mathematics. The elements of the subset can be listed in any order in a combination. The elements of the subset are listed in a specific order in a permutation.

Given that Raman and Raj go to a party each having Rs. 100, If they decide to expend Rs. 150.

The number of the spending will be calculated as,

Raman + Raj = 150

100 + 50 = 150
