Answer:
C)
Step-by-step explanation:
a = 7 ft, b = 3 ft, c = 5 ft (Given)
Therefore, a + b + c = 7 + 3 + 5 = 15 ft
Let's calculate semi Perimeter of the triangle which is given by s
Now, by Heron's formula, area of triangle ABC is given as:
The awnser to ur question is A because take 2.3 time 3 and get 6.9 and then add the 108 and -3 and get 105
(2 + x) x (2x-5) = 56
(2+x)(2x-5)=56
2x² - x - 10 = 56
+10 +10
2x² - x = 66
2x² - x - 66 = 0
x = 6
2(6)² - (6) = 66
2(36) - 6 = 66
72 - 6 = 66
66 = 66
Answer:
No solutions
Step-by-step explanation: BTW put / instead of over
when you put it in y=mx+b form you get:
y=2 over 3x+30
x=-20+2y over 3
you then put:
x=-20+2(2 over 3x+30) over 3
and get no solution!
