63 dog is what I would think,
they are congruent
Answer:
-7 > x
Step-by-step explanation:
first we expand the brackets so it will be -3x -6>-69-12x
then we can convert the > to = so it will be :
-3x -6=-69-12x
we can now try to solve the equation for x so :
-3x -6= -69-12x
-6 = -69-9x
63 =-9x
7 = -x
-7 = x
we can then change the symbols back so it will be:
-7 > x
We are given with three lengths of a triangle expressed in terms and variables: (3x – 4) feet, (x^2 – 1) feet, and (2x^2 – 15) feet. The perimeter of the triangle is equal to the sum of the three sides of the triangle. In this case, the sum is 3x^2 + 3x -20. When x is equal to 4, we substitute <span>3*16 + 3*4 -20 equal to 40 feet.</span>
Answer:
B
Step-by-step explanation:
- He adds 5 coins each month
- x represents the number of months
>60 means greater than 60
So the inequality would be 30 + 5x > 60
