Answer:

Shapes are similar when one can be scaled to be like another one. Circles are always the same shape and they only vary in size. A very small circle can be expanded to be the same size as any other without changing it's shape, only size. However this is not true for ovals since they come in different shapes.

Answer:

$a^{2}(24a^{2}+36a+12)$

Step-by-step explanation:

Area of rectangle= Length*Width

so $(6a^{2}+9a+3)*4a^{2}$ multiply each coefficient of a times 4a^2

$24a^{4}+36a^{3}+12a^{2}$ then take a^2 common factor so it will be

$a^{2}(24a^{2}+36a+12)$ =area

777dan777 [17]

Answer: 3

Step-by-step explanation:

The formula for finding equation of a line in slope - intercept form is given as :

$y = mx + c$

Where m is the slope and c is the y - intercept.

Equation given :

$y = 3x + 2$ , comparing with $y = mx + c$ ,

$m = 3$

Therefore , slope = 3

X/3/4 = 100<br> what does x equal

Crank

Answer:

x=1200

Step-by-step explanation:

x/3/4=100

Step 1: Multiply both sides by 4.

x/3/4=100

(x/3/4)*(4)=(100)*(4)

x/3=400

Step 2: Multiply both sides by 3.

3*(3/x)=(3)*(400)

x=1200
