Answer:

This is a help site, so I'll explain each property and see if you can match them yourself.

Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.

Commutative Property of Addition - same as the associative property but with 2 numbers.

Identity Property of Multiplication - Any number multiplied by one is itself

Multiplicative Property of Zero: x * 0 = 0

Associative Property of Multiplication - Same as that of addition, yet with multiplication.

Distributive Property: Factoring Out.

EX: (12 x 15) = 3(4 x 5)

Price of iPad = $480

Sales tax on iPad = $31.20

Sales tax rate = \frac{sales\ tax}{Price\ of\ iPad}*100

Sales\ tax\ rate=\frac{31.20}{480}*100\\Sales\ tax\ rate=\frac{3120}{480}\\Sales\ tax\ rate=6.5\%

PIT_PIT [208]
Hey there! :)

The formula for finding volume of a sphere = 4/3 · π · r³

Radius = 1
1³ = 1 × 1 × 1 = 1

π = 3

3 × 1 = 3

3 × 4/3 = 12/3 = 4

The volume is 4 in³

Hope this helps :)

Which group was founded to prevent African Americans from exercising their civil rights? the Whig Party the Ku Klux Klan the Pop
Cloud [144]

The group founded to prevent African Americans from exercising their civil rights was the Ku Klux Klan.

<u>Explanation:</u>

The Civil Rights Act of 1866 made African Americans(Radical Republicans) citizens of the US, prohibiting them from discriminating, which must be enforced in federal courts.

The Ku Klux Klan, generally known as the KKK or Klan, is an American white supremacist party that has the main goal of targeting the African people. The three eras of Klan are namely,

  • First Klan: 1865–1871
  • Second Klan: 1915–1944
  • Later Klans: 1950s–present

Each era has favored radical reactionary positions, such as white nationalism, anti-immigration and, in particular, the subsequent revivalism: Nordism and anti-Catholicism.

X^2 +6x+30 in vertex form
Elina [12.6K]

Answer:

Step-by-step explanation:

Factoring  x2-6x-30

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -30

Step-1 : Multiply the coefficient of the first term by the constant   1 • -30 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   -6 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7

     -2    +    15    =    13

     -1    +    30    =    29
