P² - 12 p - 13 = 0 

Δ = ( -12)² - 4 ( 1 * - 13) 
Δ = 144 + 52
Δ = 196 = 14²

x₁ = (- ( -12) + 14 ) / 2 = 26/2 = 13 
x₂ = ( - ( -12) - 14) /2 = - 2 /2 = - 1

Answer:

The solutions of the given equations are -1 and 13.

Step-by-step explanation:

The given equation is

p^2-12p=13

Subtract 13 from both the sides.

p^2-12p-13=0

Middle term can be written as -13p+p,

p^2-13p+p-13=0

p(p-13)+1(p-13)=0

(p+1)(p-13)=0

Using zero product property, equal each factor equal to 0.

p+1=0\Rightarrow p=-1

p-13=0\Rightarrow p=13

Therefore the solutions of the given equations are -1 and 13.

A new sidewalk will be 5 feet​ wide, 100 feet​ long, and filled to a depth of 3 inches ​(0.25 ​foot) with concrete. How many cub
GarryVolchara [31]

Answer:

4.63 cubic yard.

Step-by-step explanation:

Given,

The length of sidewalk, l = 100 feet,

Width, w = 5 feet,

Depth, h = 3 inches = 0.25 feet,

Thus, the volume of the concrete needed for making the sidewalk,

V=l\times w\times h

=100\times 5\times 0.25

= 125 cubic feet,

∵ 1 cubic yard = 27 cubic feet,

⇒ 1 cubic feet = \frac{1}{27} cubic yard,

Thus, the quantity of concrete needed = \frac{125}{27} ≈ 4.63 cubic yard.

HELP PLEASEE!!!!
ss7ja [257]

Answer:

See below ~

Step-by-step explanation:

\textsf {Each of the steps has been reasoned below :}

\implies \textsf {3x - 2 = 4 (Given)}

\implies \textsf {3x = 6 (Addition Property of Equality)}

\implies \textsf {x  = 2 (Division Property of Equality)}

\textsf {In the second step, the property has been applied}\\\textsf {by adding 2 to each side of the equation.}

\textsf {In the third step, the property has been applied by dividing 3 on each side.}
