Answer:
a=9, c=19
Step-by-step explanation:
Aight so basically in 30, 60, 90 triangles there is a formula for the sides
the hypotenuse(the longest side)=2a
The tiny side (the smallest side)=a
and the middle child =
Based on that we see that a is 9
and since c=2a then it's 18
Answer:
Below.
Step-by-step explanation:
(a). The x estimations of the turning points are -1.8 and 1.1, according to the graph.
(b). Where the graph crosses the x axis are the solutions. x = -3, 0, and 2 are the values.
Answer:
Step-by-step explanation:
9x+8x+5+11= 17x+16
-5x-2x-7+6= -7x-1
-x-5x-9-4= -6x-13
3x-x-4+7= 2x+3
7x-5x+4-5= 2x-1
2x+7x-3+11= 9x+8
-4x+6x-5-8= 2x-13
12x-2x-14-3= 10x-17
5x-5x+4-12= -8
Hope this helps (brainliest is appriciated)
