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

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.

= 1/2

y = 1/2x + b

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

Answer:

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
