Answer should be: X = 4, -5
Answer:
14 x 14 = 196
10 x 14 x 1/2(basically just dividing by 2) = 70
70 x 4(four sides of triangles) = 280
Now let's add the areas together:
196 + 280 = 476 cm^2 is your answer.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

The solution of the inequality is the shaded area above the dashed line
The equation of the dashed line is 
The slope of the dashed line is positive (m=5/3)
The x-intercept of the dashed line is (3.6,0) (value of x when y is zero)
The y-intercept of the dashed line is (0,-6) (value of y when x is zero)
therefore
using a graphing tool
The graph in the attached figure
there are 4 aces and 4 9's for a total of 8 cards
there is a total of 52 cards
so 9/52 is the probability
