Answer:
m = 1/2
Step-by-step explanation:
slope = m
m= y1-y2/x1-x2
y1= -2
y2= 1
-2-1 = -3
x1= -3
x2=-3
-3-3 = -6
-3/-6 = 1/2
Im going to say B.)
I hope I'm correct
Answer:
8x^2 + 34; 45.52 centimeters
Step-by-step explanation:
The perimeter is twice the sum of adjacent edges of a rectangle:
P = 2((2x^2 +9) +(2x^2 +8)) = 2(4x^2 +17)
P = 8x^2 +34
Then when x=1.2, the perimeter is ...
P = 8(1.2^2) +34 = 8·1.44 +34 = 45.52 . . . . cm
Answer: X=4
Step-by-step explanation:
Because the 90 angle is alternate exterior angle to the 21x+6. So they are equal to each other. It would be 90=21x+6. Then -6 to both sides to be 84=21x and 84/21 is 4. So X=4.
