Answer:
x = -5
x = -12
Step-by-step explanation:
- 7x - 60 = x^2 + 10x
add 7x to both sides
x^2 + 17x = -60
add 60 to both sides
x^2 + 17x + 60 = 0
factorise quadratic
(x + 12) (x + 5) = 0
<em>x = -12</em>
<em>x = -12x = -5</em>
Answer : 4
Explanation : you minus the 2 on both sides bc they have the same "last name" by doing this you get 12 on the left and elimination 2 on the right which leaves you with 12=3x. Divide 3 on both sides which 12/3 =4 and ur left with x. So the final equation is 4=x
Answer:
s = (14 + 7 + 11)/2 = 32/2 =16
=> area = sqrt(16*(16-14)*(16-11)*(16-7)) = ~37.95
=> h = 2*Area/Base = 2*37.95/14 = 5.42
If you are asking about the percent then it would be 83.33%
