60 is 5/6 of what number?

Stels [109]

If x = the number you are trying to find:
$60 = \frac{5}{6} * x$
$\frac{60}{ \frac{5}{6} } = x$
and when dividing by a fraction you can flip it and multiply instead:
60 * 6/5 = 72
The number is 72

1. Find the product: (x + 2)( x – 2)

Digiron [165]

Answer:

Part 1) Option C $x^{2}-4$

Part 2) Option A $(x+6)(x-6)$

Part 3) Option C $(2x+9)(2x-9)$

Part 4) Option C Prime

Part 5) Option C $2(x+3)(x-3)$

Part 6) Option A $3(x^{2} -7)$

Step-by-step explanation:

we know that

A difference of square can be factored in the form

$a^{2}-b^{2}=(a+b)(a-b)$

Part 1) Find the product: $(x + 2)( x - 2)$

Applying difference of square

$(x + 2)( x - 2)=x^{2}-2^{2}$

$(x + 2)( x - 2)=x^{2}-4$

Part 2) Factor Completely: $x^{2} -36$

Applying difference of square

$x^{2} -36=(x+6)(x-6)$

Part 3) Factor Completely: $4x^{2} -81$

Applying difference of square

$4x^{2} -81=(2x+9)(2x-9)$

Part 4) Factor Completely: $x^{2} +16$

Is not a difference of square

Is prime

therefore

Is not possible to factored

Part 5) Factor Completely: $2x^{2} -18$

$2x^{2} -18=2(x^{2} -9)$

Applying difference of square

$2(x^{2} -9)=2(x+3)(x-3)$

Part 6) Factor Completely: $3x^{2} -21$

Is not a difference of square

$3x^{2} -21=3(x^{2} -7)$

Helpp please! i don't understand this

MissTica

Answer:

Step-by-step explanation:

Remark

This is actually a six sided figure. That really doesn't matter, but it's interesting to observe. It goes a long way to explaining what is going on. The trick to exterior angles is that as long as the figure is convex ( a closed figure whose lines do not cross), the exterior angles add to 360.

Once you know that, then you know that this figure must have 6 exterior angles and no matter how they are made, their total is 360.

Equation

n + n + n + n + 90 + 90 = 360 Combine like terms.

Solution

4n + 180 = 360 Subtract 180

4n = 360 - 180

4n = 180 Divide both sides by 4

4n/4 = 180/4

n = 45

Note

Not a simple problem. Thanks for posting
