Answer:4x^2+22x-12
Step-by-step explanation:
height=(2x+12)
base=(4x-2)
Area of =(base x height)/2
Area of =((4x-2)(2x+12))/2
Area of =(8x^2+48x-4x-24)/2
Area of =(8x^2+44x-24)/2
Area of =4x^2+22x-12
Answer: 1 minute and 43 seconds faster
Step-by-step explanation:
you have it right 5 is 1 you just divide it by 10 again but for #7 and 10 its 8 over 10 and 6 over 10 cause its not in the 10s yet hope i helped
X liters of 10% + (30 - x) liters of 22% = 30 liters of 15%
<span>Plugging in the numbers </span>
<span>x(10) + (30 - x)22 = 30(15) </span>
<span>Distribute </span>
<span>10x + 660 - 22x = 450 </span>
<span>Combine like terms </span>
<span>-12x = -210 </span>
<span>Divide both sides by -12 </span>
<span>x = 17.5 </span>
<span>30 - x = 12.5 </span>
<span>17.5 liters of 10% + 12.5 liters of 22% = 30 liters of 15%
THE TRICK IS TO JUST USE ONLY ONE VARIABLE</span>
Answer:
A. the total amount of the budget given to the country
Step-by-step explanation:
In order to know the answer, you have to check what the<em> y-axis</em> represents. In the graph above, it represents the "Budget Remaining," which is expressed in <em>thousands of dollars. </em>On the other hand, the<em> x-axis</em> represents the "Time," which is expressed in<em> months</em>.
Point (0,18) shows the total amount of the budget for the Cultural Events in the country. It starts at 18,000 dollars and decreases as months pass by. This is shown by the graph's <em>"negative slope."</em> This means that<u> as the number of months increases, the amount of money decreases.</u>
