Simplify the sum. (2u^3 + 6u^2 + 3) + (2u^3 - 7u + 6)

Answers

Answer 1
Answer: Steps:

1) Group the like terms and simplify.

2) Do follow the BODMAS Rule. Simplify terms inside the brackets, first. Then, follow this serial: Division, Multiplication, Addition, Subtraction.

Method:

(2u^3 + 6u^2 + 3) + (2u^3 - 7u + 6)

= 2u^3 + 6u^2 + 3 + 2u^3 - 7u + 6

= 2u^3+2u^3+6u^2-7u+3+6

= (2u^3+2u^3)+6u^2-7u+(3+6)

= 4u^3+6u^2-7u+9

If a right angle triangle has a hypotenuse of length 13 units and a leg of length 7 units, what would be the length of the other leg?

Answers

The length of the other leg of a right angle triangle is, 10.95 units

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

A right angle triangle has a hypotenuse of length 13 units and a leg of length 7 units.

Now, By the Pythagoras theorem, we get;

⇒ Hypotenuse² = Perpendicular² + Base²

⇒ 13² = 7² + Base²

⇒ 169 = 49 + Base²

⇒ Base² = 169 - 49

⇒ Base² = 120

⇒ Base = √120

⇒ Base = 10.95 units

The first term of an arithmetic sequence is -5, and the tenth term is 13. Find the common difference.1.8

8/9

Answers

Answer:

d = 2

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 5 and a₁₀ = 13, thus

a₁ + 9d = 13, that is

- 5 + 9d = 13 ( add 5 to both sides )

9d = 18 ( divide both sides by 9 )

d = 2
