Answer:

Width = 7 cm.

Step-by-step explanation:

Create your equation. 2x + 2(2x + 17) = 76

Distribute 2 to 2x and 17. 2x + 4x + 34

Combine like terms. 6x + 34 = 76

Subtract 34 from both sides.

6x = 42

Divide both sides by 6.

x = 7

The base of the triangle decreases by 30% and the height increases by 20%.
sergeinik [125]

Answer:

Area decreases by 16%

Step-by-step explanation:

Use formula for the area of the triangle

A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}

<u>Initial triangle:</u>

The base is 18 cm

The height is 5 cm

The area is

A_{initial}=\dfrac{1}{2}\cdot 18\cdot 5=45\ cm^2

<u>New triangle:</u>

The base is (1-0.3)\cdot 18=0.7\cdot 18=12.6\ cm

The height is (1+0.2)\cdot 5=1.2\cdot 5=6\ cm

The area is

A_{new}=\dfrac{1}{2}\cdot 12.6\cdot 6=37.8\ cm^2

Area decreases by

100\%-\dfrac{37.8}{45}\cdot 100\%=100\%-84\%=16\%

If if the branding division were to experience the same percentage increase from year 2 to year 3 as they did from year 1 to yea
Sedaia [141]
Since the basis is from year 1 to year 2, calculate first for the difference of their percentages. That would be:

Difference = year 2 - year 1
Difference = 2.32% - 1.1% = 1.22%

We apply this same value of percentage increase from year 2 to year. Thus, the percentage for year 3 is:

% Year 3 = % Year 2 + percentage increase
% Year 3 = 2.32% + 1.22%
% Year 3 = 3.54%
