Answer:
x<-3
Step-by-step explanation:
-7x+6/3 >9
-7x+6 >27
-7x>27-6
-7x>21
-x>3
x<-3
Perimeter of square = 4 x l
so ATC 4 x l = 240
= 240/40= l
so 60 = l
the answer is 60 inches.
Answer:
9x^2 25x+14
Step-by-step explanation:
using FOIL:
(x+2)(9x+7)
9x^2 +7x + 18x +14
9x^2 25x+14
Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
Answer: #13: Domain = (-∞,∞) Range = (-∞,0]
