Answer:

<em>Perimeter of FGH = </em><em>192</em>

Step-by-step explanation:

42 / 28 = 1.5

50 x 1.5 = 75

44 x 1.5 = 66

34 x 1.5 = 51

75 + 66 + 51 = 192

Simplify using only POSITIVE exponents:

pickupchik [31]

So here are a few rules with exponents that you should know:

Multiplying exponents of the same base: $x^m*x^n=x^{m+n}$
Dividing exponents of the same base: $x^m\div x^n=x^{m-n}$
Powering a power to a power: $(x^m)^n=x^{m*n}$
Converting a negative exponent to a positive one: $x^{-m}=\frac{1}{x^m}\ \textsf{and}\ \frac{1}{x^{-m}}=x^m$

Firstly, solve the outside exponent:

$(2x^3y^7)^{-2}=2^{-2}x^{3*-2}y^{7*-2}=2^{-2}x^{-6}y^{-14}$

Next, convert the negative exponents into positive ones:

$2^{-2}x^{-6}y^{-14}=\frac{1}{2^2x^6y^{14}}=\frac{1}{4x^6y^{14}}$

<u>Your final answer is $\frac{1}{4x^6y^{14}}$ </u>

For this, just divide:

$\frac{12x^5y^3}{4x^{-1}}=\frac{12}{4}x^{5-(-1)}y^{3-0}=3x^6y^3$

<u>Your final answer is $3x^6y^3$ </u>

For this, convert all negative exponents into positive ones:

$\frac{r^{-7}b^{-8}}{t^{-4}w}=\frac{t^4}{r^7b^8w}$

<u>Your final answer is $\frac{t^4}{r^7b^8w}$ </u>

A figure has four sides measuring 10 centimeters, and two pair of opposite congruent angles. The image can be classified as whic

vampirchik [111]

It is a rhombus
It is so because all its sides are equalto 10cm.
opposite angles are equal. in a parallelogram opposite angles are equal but all sides aren't equal but in case of a rhombus it is so.

Penny wants to make a model of a beetle that is larger than life size. Penny says she is going to use a scaling factor of 7/12.

MakcuM [25]

It would be nonsense, as if the beetle were at normal size, then it would be considered 1/1 as a scale. If you wanted to increase it, you would increase the numerator.
