Answer:
Yes
Step-by-step explanation:
The value of x in the equation from the least to the greatest is -8 and -4.
<h3>How to find the variable in an equation?</h3>
cross multiply
x - 2 = (x + 10)(x + 3)
x - 2 = x² + 3x + 10x + 30
x - 2 = x² + 13x + 30
x² + 13x - x + 30 + 2 = 0
x² + 12x + 32 = 0
x² + 4x + 8x + 32 = 0
x(x + 4) + 8(x + 4) = 0
(x + 4)(x + 8) = 0
x = -4 and x = -8

#SPJ4
7/5 = 14/10 = 28/20
Numerator = x
Denominator = x-4
Add 3 to both:
x +3 / (x-4+3)
x+3 = 14
(x-4 +3) = 10 = x-1 = 10
x = 11
Check:
11 -4 = 7 ( denominator is 4 less than the numerator.)
add 3 to both:
11+3 = 14
7+3 = 10
14/10 reduces to 7/5
The original fraction would be 11/7
Answer:
II. a = 6 , b = 9.1 , c = 10.9
Step-by-step explanation:
I. a = 1.2 , b = 3.5 , c= 3.6
c² = a² + b²
3.6² = 1.2² + 3.5²
12.96 = 1.44 + 12.25
12.96 ≠ 13.69
These sides cannot create a right triangle.
II. a = 6 , b = 9.1 ,c = 10.9
c² = a² + b²
10.9² = 6² + 9.1²
118.81 = 36 + 82.81
118.81 = 118.81
Therefore, these sides can create a right triangle.
III. a = 6 , b = 8 , c = 9
c² = a² + b²
9² = 6² + 8²
81 = 36 + 72
81 ≠ 108
These sides cannot create a right triangle.
