Answer:

2x(x+y)(x-y)

Step-by-step explanation:

Given the expression;

(x+y)² + 2(x+ y)(x- y) + (x– y)²

Factorize

(x+y)² + (x+ y)(x- y) +   (x+ y)(x- y) + (x– y)²

= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]

= (x+y)(x-y)(x+y+(x-y))

= (x+y)(x-y)(x+y+x-y)

= (x+y)(x-y)(2x)

hence the expanded form is 2x(x+y)(x-y)

Answer:

12

Step-by-step explanation:

"6 times as many birds..." in other words 6 x 2

The number of turtles that was sold by the pet store given the number of birds sold is 12.

Multiplication is a mathematical operation that involves determining the product of two or more numbers. The sign used to represent multiplication is x.

Number of turtles were sold = 2 x 6 = 12

Answer:

12.75feet (12¾)

Step-by-step explanation:

7t+1+5t+8=162feet

12t+9=162feet

12t=162-9

=153

t = 153÷9

=12.75feet (12¾feet)

Answer:

A = 28.3 cubic inches; P = 20.1 inches

Step-by-step explanation:

Looks like 3/4 of a full circle

The area of a circle is calculated with the formula: [tex]\pi r^{2}[/tex]

Since the problem wants pi = 3.14, we use 3.14 instead of pi in the equation.

The radius is given as 3 inches

Area = [tex]3.14*3^{2} = 3.14*9 = 28.26[/tex] cubic inches = 28.3 cubic inches

------------------------

Perimeter is calculated with [tex]2\pi r[/tex].

But this is 3/4 of a circle with an additional two 3-inch sides

Perimeter = [tex]\frac{3}{4}*2\pi r[/tex] + 2(3) = 14.1 + 6 = 20.1 inches

Step-by-step explanation:

Answer:

350

Step-by-step explanation:

so the first step is to find the values of each of them

7x10^6=7000000

2x10^4=20000

then we divide 7000000 by 20000

7000000/20000=350

so the answer is 350

Answer:

(n + 1) (5m + 4)

Step-by-step explanation:

⇒ (n + 1) (5m + 4)

⇒ 5mn + 4n + 5m + 4

⇒ 5mn + 5m + 4n + 4

Answer:

(n + 1)(5m + 4)

Step-by-step explanation:

Given

5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )

= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term

= (n + 1)(5m + 4)

Answer:

y=67.7 Degrees

Step-by-step explanation:

You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:

Tan(y)= 100/41

We then inverse tan to isolate y

y=tan^-1 100/41

y=67.7 Degrees

I believe its a triangular prism

Answer:

Triangular Prism

Step-by-step explanation:

Fold the shape at the dotted lines and you will see what shape it is. It's hard to explain but look up Triangular Prism and it will make sense.  

Answer: Yes, it'll be approved

Step-by-step explanation:

To solve this, we.need to calculate 2/9 of 78 states. This will be:

= 2/9 × 78

= 17 states

Since 21 states approve an​ amendment, then the constitution will be​ amended because the number of states is more than 2/9 of the 78 states

Answer:A he is correct because the inner circle is a dilation of the outer circle

Step-by-step explanation: just did the test

The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.

The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.

Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.

Troy is accurate if he claims the two circles are similar.

Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Answer:

[tex]\frac{20}{13}[/tex] + [tex]\frac{5}{13}[/tex] [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{5}{4-\sqrt{3} }[/tex]

To rationalise the denominator, multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of 4 - [tex]\sqrt{3}[/tex] is 4 + [tex]\sqrt{3}[/tex]

= [tex]\frac{5(4+\sqrt{3}) }{(4-\sqrt{3})(4+\sqrt{3}) }[/tex]

= [tex]\frac{20+5\sqrt{3} }{16-3}[/tex]

= [tex]\frac{20+5\sqrt{3} }{13}[/tex]

= [tex]\frac{20}{13}[/tex] + [tex]\frac{5}{13}[/tex] [tex]\sqrt{3}[/tex]
