What is the value of the expression (2.75) (5.2)?

Answer:

.47 because 7/15 is 0.466

Step-by-step explanation:

We want to see where Oliver is making a mistake in his claim.

The correct option is the first one, the simplification on the last step is wrong.

We start with the expression:

[tex]tan( \frac{3*pi}{4} + x)[/tex]

Now, by looking at Olvier's work, we can see that on the last step he writes:

[tex]\frac{-1 + tan(x)}{1 + tan(x)} = -1[/tex]

This is clearly wrong, as the numerator and the denominator are dont simplify to -1 (this only happens if the numerator is -1 times the denominator), so the left side can't be equal to -1, it actually would be simplified to:

[tex]\frac{-1 + tan(x)}{1 + tan(x)} = \frac{-1 +1 - 1 tan(x)}{1 + tan(x)} = \frac{-2 + 1 + tan(x)}{1 + tan(x)} \\\\\frac{-2 + (1 + tan(x))}{1 + tan(x)} = \frac{-2 }{1 + tan(x)} + \frac{ 1 + tan(x)}{1 + tan(x)} = \frac{-2 }{1 + tan(x)} + 1[/tex]

Then the correct option is the first option.

Answer:

y = 1/2x - 1

Step-by-step explanation:

y2 - y1 / x2 - x1

-2 - 2 / -2 - 6

-4 / -8

= 1/2

y = 1/2x + b

-2 = 1/2(-2) + b

-2 = -1 + b

Answer to the first part:  8a³b + 4ab

Step-by-step explanation:

Perimeter = distance around the three sides

P = 6a³b + 2a³b + 4ab

P = (6a³b + 2a³b) + 4ab           add like terms

P = 8a³b +4ab                          Simply

The value of the perimeter and area of the triangle are,

20.52 cm²  and 28.68 cm

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

Now, By Using Pythagoras theorem to find the base of the triangle as;

a² = 6² - 3²

a ² =  27

a = √27

And, b² = 9² - 3²

b² =  72

b = √72

Hence, Base = √27 + √72

= 13.68

So, We get;

Area = 0.5 x 13.68 x 3

Area = 20.52 cm²  

And, The value of perimeter is,

Perimeter = 9 + 6 + 13.68

= 28.68

Thus, The value of the perimeter and area of the triangle are,

20.52 cm²  and 28.68 cm

Answer: x = -28

Step-by-step explanation:

1) Distribute

3(x-8)+4x=8x+4

3x-24+4x=8x+4

2) Combine like terms

7x - 24 = 8x + 4

3) Move x(subtract 7x from both sides)

-24 = x + 4

4) Subtract 4 from both sides.

-28 = x

Hope it helps :)

The simplified solution of the given expression is x = -28.

Given that, to determine the simplified solution of the expression  3(x-8)+4x=8x+4

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
3(x-8)+4x=8x+4
3x - 24 + 4x - 8x = 4
-x = 4 + 24
-x = 28

Thus, the simplified solution of the given expression is x = -28.

Answer:

Step-by-step explanation:

You have the relation ...

  (left side number) × (top number) = (number in the area box)

This means ...

  (top number) = (number in the area box)/(left side number)

  top number = 680/17 = 40 . . . number in the quotient box

and ...

  17 × 8 = number in the area box = 136

__

The number in the right-side box is the remainder, the difference between the dividend 820 and the sum of the numbers in the other two area boxes.

  820 -680 -136 = 4 . . . . number in the right-side box
