Answer: x=0.6 btw how do you put a picture into a question.
Answer:
r=-10
Step-by-step explanation:
Plug in the value of t into the equation.
r=3t-1; t = -3
r=3(-3)-1
r= -10
Perimeter = a + b + c = 30
Area = 1/2 x a x b = 30
Multiples of 30: 2, 3, 5, 6, 10, 12, 15
For perimeter c = 30- (a+b)
C= sqrt( a^2 + b^2)
Using the possible combinations of the above:
5 and 12:
C = sqrt(5^2 + 12^2) = 13
5 + 12 + 13 = 30 for the perimeter
Area = 1/2 x 5 x 12 = 30
The sides are 5, 12 and 13 cm
Since the point satisfies the equation
y = x +3
you have
b = (-3/5) +3 = 12/5 . . . . . . . matches A. 12/5
