Trying to factor by splitting the middle term

Factoring 4x2-19x-5

The first term is, 4x2 its coefficient is 4 .

The middle term is, -19x its coefficient is -19 .

The last term, "the constant", is -5

Step-1 : Multiply the coefficient of the first term by the constant 4 • -5 = -20

Step-2 : Find two factors of -20 whose sum equals the coefficient of the middle term, which is -19 .

-20 + 1 = -19 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -20 and 1

4x2 - 20x + 1x - 5

Step-4 : Add up the first 2 terms, pulling out like factors :

4x • (x-5)

Add up the last 2 terms, pulling out common factors :

1 • (x-5)

Step-5 : Add up the four terms of step 4 :

(4x+1) • (x-5)

Which is the desired factorization

Equation at the end of step

:

(x - 5) • (4x + 1) = 0

Theory - Roots of a product

3.1 A product of several terms equals zero.

When a product of two or more terms equals zero, then at least one of the terms must be zero.

We shall now solve each term = 0 separately

In other words, we are going to solve as many equations as there are terms in the product

Any solution of term = 0 solves product = 0 as well.

• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.

• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.

• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.

• When we are not given a number for the variable in the expression, we have to group like-terms.

Answer: 17/60

Step-by-step explanation:

Suppose that whe have N fishes.

We know that 1/5 of these N fishes are guppies.

We also know that 1/12 of these N fishes are goldfish.

Now, what is the fraction of guppies and goldfish together?

We only need to add the fractions:

1/5 + 1/12

This may be hard because the denominators are different, then the first step will be to write both fractions with the same denominator.

We know that:

5*12 = 60

Then we can write:

1/5 = (12/12)*(1/5) = 12/(5*12) = 12/60

and

1/12 = (5/5)*(1/12) = 5/(5*12) = 5/60

Then our previous sum:

1/5 + 1/12

can be written as:

12/60 + 5/60

and this is easy to solve:

12/60 + 5/60 = (12 + 5)/60 = 17/60

This is the fraction of the fish that are guppies or goldfish.

Answer:

Area of the square is 2916 [tex]m^{2}[/tex].

Step-by-step explanation:

Let the breadth of the rectangle be represented by w. So that;

length of rectangle = 5w

Area of rectangle = length x breadth

                             = 5w x w

1620 = 5[tex]w^{2}[/tex]

divide through by 5 to have,

[tex]w^{2}[/tex] = 324

w = [tex]\sqrt{324}[/tex]

   = 18

Thus, the breadth of the rectangle is 18 m.

length = 5 w = 5 x 18

           = 90 m

The length of the rectangle is 90 m.

Perimeter of the rectangle = 2(l + w)

                                  = 2( 90 + 18)

                                  = 216 m

Perimeter of a square = 4l

where l is the length of its side.

Given that the perimeters of the rectangle and square are equal, then;

4l = 216

l = [tex]\frac{216}{4}[/tex]

 = 54

length of the side of square is 54 m.

Therefore,

Area of square = [tex]l^{2}[/tex]

                         = [tex]54^{2}[/tex]

                        = 2916

Area of the square whose perimeter is equal to that of the rectangle is 2916 [tex]m^{2}[/tex].

Answer:

[tex]\huge\boxed{\sf x = 37}[/tex]

Step-by-step explanation:

We know that,

The sum of interior angles of a triangle is 180 degrees.

So,

2x + 4 + 2x - 9 + x = 180

5x - 5 = 180

Add 5 to both sides

5x = 180 + 5

5x = 185

Divide both sides by 5

x = 185 / 5

x = 37

Answer:

In this equation, let "x" equal the rate at which the tub will be filled. The tub holds 32 gallons, which will be one half of the equation. The tub already contains 12 gallons, so this will be half of the other side of the equation. The rate is "x" gallons per minute, and the time it required was 5 minutes, so this would be "5x". Placing all these parts together gives an equation of (32 = 5x + 12) gallons per minute dispensed.

The expression of the Earth 1.496 x 10^8 km  in standard form is 149,600,000

Standard form is a simple way of expressing very large numbers into small sizes for easier calculation.

The given information is already in its standard form as 1.496 × 10⁸ km.

We can express it in its ordinary form by shifting the decimal place to the right side in terms of the power with which it is being raised.

Answer:

Please check the explanation.

Step-by-step explanation:

We know that when two lines intersect we get a pair of opposite angles.

According to the vertical angle theorem, if two angles are vertical then the measure of each angle will be the same i.e. the angles will be congruent.

Identifying angle types:

From the figure, it is clear that

The angle (9y+7)° and (2y+98)° are opposite angles.

Hence,

Determining the equation

As the vertical angles are congruent, so

(9y+7)° = (2y+98)°

Steps solving the equation

We know the equation of vertical angles (9y+7)° and (2y+98)° such as

(9y+7)° = (2y+98)°

solving for y

9y - 2y = 98 - 7

7y = 91

divide both sides by 7

7y/7 = 91/7

y = 13

Therefore, the value of y = 13

Answer:

2, 4 6 and 8

Step-by-step explanation:

Given the range of a function expressed as ƒ(x) = -6x + 11 where x are the values of the domain

Given the follwing range f(x) =  {–37, –25, –13, –1}, we are to find the corresponding value of x;

-37 = -6x + 11

-37 - 11 = -6x

-48 = -6x

x = -48/-6

x = 8

if f(x) = -25

-25 = -6x + 11

-6x = -25-11

-6x = -36

x = -36/-6

x = 6

if f(x) = -13

-13 = -6x + 11

-6x = -13-11

-6x = -24

x = -24/-6

x = 4

if f(x) = -1

-1 = -6x + 11

-6x = -1-11

-6x = -12

x = -12/-6

x = 2

Hence required domain values are 2, 4 6 and 8
