Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area = 
8 = 
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x = 
x = 
x = 
x = 
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.
Answer:

Rates and rarios are different and yet still different
Answer:
The cost for camping is 266 pounds
The cost for camping per night is 14 pounds
The cost for camping at the second campsite would be 114 pounds more than the first one.
Per night that is 6 pounds more if you needed that.
Answer:
x = 30
y = 15
Step-by-step explanation:
<u><em>All the angles are </em></u><u><em>90°</em></u><u><em>, so set 6y and 3x equal to 90, like so:</em></u>
6y = 90
<u><em>Divide both sides by 6:</em></u>
y = 15
<u>Solving for x:</u>
3x = 90
<em><u>Divide both sides by 3:</u></em>
x = 30
