6 0

Answer:

1. A resposta é a opção C.

2. ( a +b )² = a² + 2ab + b² Verdade

( a - b )² = a² - 2ab + b² Verdade

( a + b ) .( a – b) = a² + b² Falso

( a +b)³ = a³ + 3a²b + 3ab² + b³ Verdade

( a -b)³ = a³ - 3a²b + 3ab² - b³ Verdade

3. a.) m² - 14am + 49a² = ( m - 7a)²

b) m2 – 9n² = m² - (3n)² = (m + 3n)(m - 3n)

c) 30+ 5xy + 12a +2axy = (6 + xy)(5 + 2a)

d) 8a²b + 10ab² = 2ab( 4a + 5b)

A cylindrical metal pipe has a diameter of 8.4 millimeters and
vladimir1956 [14]
Volume of a cylinder = pi x radius^2 x height of cylinder and diameter/2 is the radius so...

3.14 x (8.4/2) ^ 2 x 10 = 553.9

Since there is a hole that means you have to find the volume of the hole and subtract that from the volume of the whole pipe (553.9)

3.14 x (6/2) ^2 x 10 = 282.6

553.9 - 282.6 = 271.3

(17, -13), (17, 8)<br> What is the slope through the line
Sophie [7]

Answer:

undefined

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 8 - -13)/ ( 17-17)

   = ( 8 +13)/ ( 17-17)

   = 21/ 0

We can not divide by 0, so the slope is undefined

PLEASE HELP ME! THE QUESTION IS DOWN BELOW PLEASE PLEASE HELP ME
Basile [38]

The given expression (8h + 2w - 5h + 3w) can fully be simplified as 3h + 5w.

<h3>What is an expression?</h3>

An expression can be defined as a type of mathematical equation which is used to show the relationship that is existing between two or more variables and numerical quantities (integers).

In this exercise, you're required to fully simplify the given expression in the lowest terms. Thus, we would simplify the given expression completely by collecting like terms and performing the necessary arithmetic operations (addition and subtraction) as follows:

Collecting like terms, we have:

8h - 5h + 3w + 2w

Subtracting and adding the like terms respectively, we have:

3h + 5w.

In conclusion, we can logically deduce that the given expression (8h + 2w - 5h + 3w) can fully be simplified as 3h + 5w.

A tumor in a rat responds to a new radiation treatment by shrinking 5% with each treatment. How many treatments before the tumor
Nuetrik [128]
A quarter of its original size would be 25% of 100%, right? Therefore, the tumor would have to shrink 75%. If each treatment, the tumor shrinks 5% that would mean it takes 15 treatments to shrink 75 percent.
