Answer:

-7/8

= (7/9) × (-9/8)

=-7/8

The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2 so option 1st and 4th are correct.

Roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.

For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.

The number of roots of an equation depends on the degree of the equation for example number of roots of quadratic equation are 2.

Given the roots

01)

x = -2

square both sides

x² = 4

x² - 4 = 0

02)

x = 2

Square both sides

x² = 4

Multiply by 4 on each side

4x² = 16

Hence "The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2".

Answer:

$28.00

Step-by-step explanation:

$4.99 + $12.99 = $17.98 with 10% of discount =$16.18

$2.88 (2) + $0.79 (3) + 1.89 (2) = $11.91 with 15% of discount = $10.12

$16.18 + $10.12 = $26.30 with 6.5% sales tax = $28.00

Answer:

multiply -1.25 x 12

Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15

now -15 +651= 636

Answer:

a = 27

Step-by-step explanation:

3x + 6y = a

From the given information, 3 and 6 are the numbers of passengers that cars and vans can take. That means x and y must be the numbers of cars and vans, and a is the total number of passengers.

a = 27

Answer:

Slope = -2

Y-intercept = 13

y = -2x + 13

Step-by-step explanation:

(5-3)/(4-5) = 2/-1 = -2

3 = -2(5) + b

3 = -10 + b

b = 13

y = -2x + 13

Answer:

y = 13

Step-by-step explanation:

Y = 5 + 2x but when x = 4 you replace any X variables with 4

So the equation now is 5 + 2(4) = 5 + 8 = 13

y = 13

Answer: 31/25/50

Explanation: 31 is the second one. 6 less than second is 25 which is the first one, and third is 2x the first so 50

50 + 25 + 31 = 106

Answer:

a/2=3

We simplify the equation to the form, which is simple to understand  

a/2=3

We move all terms containing a to the left and all other terms to the right.  

+ 0.5a=+3

We simplify left and right side of the equation.  

+ 0.5a=+3

We divide both sides of the equation by 0.5 to get a.  

a=6

Answer:

1440 degrees.

Step-by-step explanation:

125 + 140 + 160 = 425 degrees.

The remaining angles are each 145.

The exterior angles of all polygons sum to 360 .

So we have exterior angles sum of the 3 given angles

= (180-125) + ( 180-140) + (180-160)

= 55 + 40 + 20 = 115.

So the remaining vale of the sum is 360 - 115

= 245 degrees.

An internal angle of 145 will give an external one of 35 degrees.

245/35 = 7.

So there are 7 145 degree angles in the polygon.

Sum of the interior angles is therefore:

425 + 7*145

= 1440 degrees.

This is a 10 sides polygon ( a decagon).

Perimeter:-

[tex]\\ \sf\longmapsto 2(40+30)[/tex]

[tex]\\ \sf\longmapsto 2(70)[/tex]

[tex]\\ \sf\longmapsto 140m[/tex]

Area

[tex]\\ \sf\longmapsto LB[/tex]

[tex]\\ \sf\longmapsto 40(30)[/tex]

[tex]\\ \sf\longmapsto 1200m^2[/tex]

= 2(Length + Breadth)

= 2(40 + 30)

= 2(70)

= 140m

= Length × Breadth

= 40 × 30

= 1200m^2

Therefore, The perimeter of the rectangle is 140m and the area of the rectangle is 1200m^2.
