Answer:

The sum of the roots is 13 and their product is 6.

Step-by-step explanation:

Use Vieta's Theorem

x1+x2=-b/a which is 39/3=13

x1*x2=c/a which is 18/3=6

Therefore, the sum of the roots is 13 and their product is 6.

The value of x can be found by using Pythagorean theorem

Base on images of the right triangles in the Unit 7 Right

triangles homework, we have;

1. The lengths of the legs of the right triangles are;

10 and 7

According to Pythagorean theorem, the hypotenuse, x, is given as follows;

2. The length of the hypotenuse = 21

Length of the a leg = 19

3. Length of the hypotenuse = 27

Length of a leg = 16

Therefore;

4. Length of the legs are; 12.8 and 5.3

Therefore;

5. The two triangles formed by the perpendicular to the side

with length 18 are similar according to Side-Angle-Side

similarity postulate.

Therefore;

The perpendicular line is a perpendicular bisector to the side

having a length of 18 (divides the segment into two).

The leg lengths of the right triangle that has x as the

hypotenuse side are; 9 and 20

Therefore;

6. The given figure is an isosceles trapezoid.

The base length, l, of the right triangle that has 19 as the

length of the hypotenuse side is; l = √(19² - 17²) = √(72) = 6·√2

According to the properties of an isosceles trapezoid, the

base length of the two right triangles are congruent.

Length of x = 31 - The base length of the two right triangles

Which gives

Therefore;

7. Height of the triangle, h = √(22² - 16²) = √(228) = 2·√(57)

The height of the triangle is a leg of the right triangle that has

x as the length of the hypotenuse side.

The other leg length = 44 - 16 = 28

Therefore;

Step-by-step explanation:

Good luck men

The equation is 2.5x + 2y - 2 = 0.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

He bought 2.5 pounds of apples that are x dollars a pound.

And 2 bags of lettuce for y dollars each.

The total cost is $2.

The equation of this.

He bought 2.5 pounds of apples that are x dollars a pound.

Then the expression is 2.5x

And 2 bags of lettuce for y dollars each.

Then the expression is 2y

The total cost is $2.

Then the expression will be

    2.5x + 2y = 2

2.5x + 2y - 2 = 0

Thus the equation is 2.5x + 2y - 2 = 0.

The area of a triangle is found by multiplying the height and base of a triangle then dividing it by two since you can use that same formula to find a rectangle but not dividing. A rectangle you multiply the base and height while a triangle will equal half the area of that rectangle

Answer:

-3/4

Step-by-step explanation:

The rate of change is the change from each perfect point to another.
Here, the points are (0,3) and (4,0).

To get from (0,3) to (4,0), you must go down 3 units and over to the right 4 units. This is the unit of change or -3/4 in this case.

Answer: -3/4, from y = -3/4 x + 3

Step-by-step explanation: The answer is based on the y=mx+b format, 3 being b. You find b on the (0,—), the center y axis. You know it’s negative because as it moves towards the larger numbers on the x axis, the slope is decreasing. Then you connect how many times the slope goes down and over as a whole number. It goes down 3 times and over 4 times. This helps you identify the slope and the function.

Answer:

-25.5

8x3=24

but we still have the .5 so we multiply that by 3 which equals to 1.5 add that to 24 which makes 25.5 and because only one of the numbers was negative it turns 25.5 into -25.5.

Answer:

A) (3x+5)(x-6)

B) x=6, -5/3

C) sorry kid, no idea

Step-by-step explanation:

Answer:

a: The factored form of the trinomial is 3x(x-6) +5 (x -6)

b: x =6 , or-5/3

c : they relate because: (3x+5)(x-6)

3x +5=0 x-6=0

3x = -5 x =6

x=-5/3,x =6

Answer:

162

Step-by-step explanation:

The number of gold coins you have is 162

Let

the number of treasure chest = x

He tried to put 18 gold coins in each treasure chest, but that left 4 treasure chests empty.  Therefore,

So he puts 12 gold coins in each treasure chest but then had 6 coins extra. Therefore,

18x - 72 = 12x + 6

18x - 12x = 6 + 72

6x = 78

divide both sides by 6

x = 78 / 6

x = 13

Therefore, the number of gold coins can be computed as follows:

Answer:

The number of pennies in the bank is 42

Step-by-step explanation:

Solution:

Given that ratio of pennies to quarters in a piggy bank is 14 : 3

Let 14x be the number of pennies in a piggy bank

Let 3x be the number of quarters in the piggy bank

To find: number of pennies

Given that there are 51 quarters

number of pennies in piggy bank + number of quarters in piggy bank = 51

14x + 3x = 51

17x = 51

x = 3

number of pennies = 14x = 14(3) = 42

Thus the number of pennies in the bank is 42
