Mathematics

Len [333]3 years ago
6 0

Answer:

Many of these are just the same equation in different orders.

42 + 6 = 48

6 + 42 = 48

48 = 6 + 42

48 = 42 + 6

42 = 48 - 6

48 - 6 = 42

6 = 48 - 42

48 - 42 = 6

How do you solve this problem? (x+3) cubed
Lubov Fominskaja [6]
You would expand becausee it isn't equal to anything

(x+3)^3=(x+3)(x+3)(x+3)
we can use binomial theorem or pascal's triangle
anyway, pascal's triangle is more practicl for this one

so
for the 3rd power
(a+b)^3=1a^3+3a^2b^1+3a^1b^2+1b^3

a=x
b=3

(x+3)^3=1x^3+3x^2(3^1)+3x^1(3)^2+1(3)^3=
x^3+9x^2+27x+27

Find the surface area of the cylinder (please help)
Misha Larkins [42]

Answer:

surface area we can also take it as total surface area

9 is the radius and 5cm is the height . as they asked total surface area we have to take the area of base so tht we can make it as

total surface area = csa of cylinder + area of base

we know that,

2pirh+pir²

pir(2h+r)

pir(2×5+9)

pir(10+9)

pir(19)

22/7×9×19

3762/7

=> 537.42 cm² is the answer.

MakcuM [25]
This is Scientific Notation here's what you have to do:

First find the Notation:

8.23×10^5

It positive so go to the right.

=823000.

Next do the same thing but with the next Notation:

3.19×10^8

Its positive so go to the right:

=319000000.

Then compare the Notation's

823000. and 319000000.

319000000. is bigger than 823000.

So your answer is 319000000. so its United States.

18 Geometry question: Use an algebraic equation to find the measure of each angle that is representative in terms of X
Dmitrij [34]

Answer:

12x - 28° = 116°

7x + 32° = 116°

Step-by-step explanation:

12x - 28° and 7x + 32° are vertical angles. Vertical angles are congruent.

Therefore, to find the measure of each angle, we have to set each equation equal to each other as follows:

12x - 28° = 7x + 32°

Collect like terms

12x - 7x = 28 + 32

5x = 60

Divide both sides by 5

5x/5 = 60/5

x = 12

✔️12x - 28°

Plug in the value of x

12(12) - 28

= 144 - 28

= 116°

✔️7x + 32°

7(12) + 32

= 84 + 32

= 116°
