When a figure is dilated, this means the corresponding sides of the shape is enlarged in a uniform multiple. In this case, the ratio of the sides remains the same. Thus, when ratio of the sides remain the same, the corresponding angles are also congruent in the dilated figure. The answer here is B. similar

We can use the Front Outside Inside Last (FOIL) method to expand the double bracket

$(3x+5)(5x-1)$

Front ⇒ $(3x)(5x)=15 x^{2}$
Outside ⇒ $(3x)(-1)=-3x$
Inside ⇒ $(5)(5x)=25x$
Last ⇒ $(5)(-1)=-5$

Put the four terms together we have
$15 x^{2} -3x+25x-5$ , then collect like terms
$15 x^{2} +22x-5$

The can of tomatoes is three times as tall but one-third as wide as the can of tuna. What is true about the areas of their label

yulyashka [42]

Problem One
Call the radius of the second can = r
Call the height of the second can = h

Then the radius of the first can = 1/3 r
The height of the first can = 3*h

A1 / A2 = (2*pi*(1/3r)*(3h)] / [2*pi * r * h]

Here's what will cancel. The twos on the right will cancel. The 3 and 1/3 will multiply to one. The 2 r's will cancel. The h's will cancel. Finally, the pis will cancel

Result A1 / A2 = 1/1
The labels will be shaped differently, but they will occupy the same area.

Problem Two
It seems like the writer of the problem put some lids on the new solid that were not implied by the question.

If I understand the problem correctly, looking at it from the top you are sweeping out a circle for the lid on top and bottom, plus the center core of the cylinder.

One lid would be pi r^2 = pi w^2 and so 2 of them would be 2 pi w^2
The region between the lids would be 2 pi r h for the surface area which is 2pi w h

Put the 2 regions together and you get
Area = 2 pi w^2 + 2 pi w h

Add 6x+2y + y2 +6x+2y +y2+ 4x2+ x2+y

Alexus [3.1K]

Answer:

5 x^2 + 2y^2 + 12x + 5y

Step-by-step explanation:

6x + 2y +y^2 + 6x + 2y + y^2 + 4x^2 + x^2 + y

12x +y^2 + 4y + y^2 + 4x^2 + x^2 + y

12x + 2y^2 + 4x^2 + x^2 + 5y

2y^2 + 5x^2 + 12x + 5y

5 x^2 + 2y^2 + 12x + 5y
