Step-by-step explanation:
<em>Given:</em>
<em>Which expression is equivalent to -6x + 7.5?</em>
<em>Solution:
Going through all answer choices:</em>
<em>[A] -3(2x-2.5)</em>
<em>Simplify</em>
<em>-6x + 7.5</em>
<em />
<em>[B] -3(2x + 2.5)</em>
<em>Simplify</em>
<em>-6x - 7.5</em>
<em />
<em>[C] -3(2x-7.5)</em>
<em>Simplify</em>
<em>-6x+22.5</em>
<em />
<em>[D] -3(2x + 7.5)</em>
<em>Simplify</em>
<em>-6x - 22.5</em>

Answer:



Step-by-step explanation:
Given
The attached triangle
Required
Find h, x and y
Let the base of the triangle be 15.
So, the area is:




Let the base of the triangle be 25.
So, the area is:



Substitute 

Solve for h



Considering the smallest triangle

So:


This gives:


Take square roots


Solving for y




<span>Martin deposits $200
in a savings account that earns 5% annual interest.
year interest balance
1 200 * 5% 200(1.05)
2 200(1.05) * 5% 200(1.05)^2
3 200(1.05)^2*5% 200(1.05)^3
y 200(1.05)^y
=> m = 200 (1.05)^y
