Answer:
Yes it's a right triangle
Step-by-step explanation:
IF it's a right triangle
a² + b² will equal c²
-----------------------
25.5² = 650.25
12² + 22.5² = 650.25
Therefor this IS a right triangle
Answer:
The answer is 95°!
Step-by-step explanation:
180°-60°-25°= 95°
The roots of the equation are 2 and k
substituting x=2 in the equation
(x+4)(x-p) = 2-x
(2+4)(2-p) = 2-2
6(2-p) = 0
dividing 6 both side, the answer is
p = 2
substituting x in the equation we
(x-4)(x-p) = 2-x
x² - 2x + 4x- 8 = 2-x
x² - 2x + 4x -8 -2 -x = 0
x² + 3x - 10 = 0
x² + 5x -2x - 10 = 0
x(x + 5) -2( x + 5) = 0
(x + 5)( x - 2) =0
(x + 5) = 0 or (x - 2) = 0
x = -5 and x = 2
therefor k = -5 and p = 2
Answer:
-12
Step-by-step explanation:
If it's a negative exponent for example -6 the answer would be 1/x^-6. So if x is 10. Then 10^-6 is equal to 1/10^6 (One over ten to the power of 6 or One divided by 10 to the power six)
