∆ABC=∆DEF

AB=DE –>String

BC=EF–> Rib

m<C=m<F=90° –>List

AC=DF

So m<A=m<D=35 (It is not clear whether the number is 35 or 36, but the same number)

Solve the equation p^2 + 4p = 1 by completing the square.

igor_vitrenko [27]

Answer:

p = -2 ±sqrt( 5)

Step-by-step explanation:

p^2 + 4p = 1

Take the coefficient of p

Divide by 2

4/2 =2

Square it

2^2 = 4

Add it to each side

p^2 + 4p+4 = 1+4

(p+2) ^2 = 5

Take the square root of each side

sqrt((p+2) ^2) =±sqrt( 5)

p+2 = ±sqrt( 5)

Subtract 2 from each side

p+2-2 = -2 ±sqrt( 5)

p = -2 ±sqrt( 5)

HELP! SIMPLIFY!

1) (m³n⁵)(mn⁴)
-----------------
m⁻³n²

Simplify.

m⁴n⁹
-------
m⁻³n²

When the bottom power is a negative, you add it to the power on top, & when the power is a positive, you subtract it.

m⁴ + m³ = m⁷

n⁹ - n² = n⁷

So, our answer for #1 is m⁷n⁷

2) 6a²b³
---------
4a

Please read rules in #1.

6 / 4 = 3/2 & a² - a = a

So, our answer is 3a
-----
2

3) 5⁶a⁶b³
---------
5²ab³
5⁶ - 5² = 5⁴ AND a⁶ - a = a⁵ AND b³-b³ = 0

So, our answer is 5⁴a⁵

Simplify 5⁴

5 × 5 × 5 × 5 = 625

So, our final answer is :

625a⁵

A line contains the points (34, 12) and (32, 48) .

inessss [21]

Slope formula : y2 - y1 / x2 - x1

( 34 , 12 ) and ( 32 , 48 )

48 - 12 / 32 - 34

36 / - 2

slope = - 18
