Answer:
These equations are equivalent because after you solve the equation the answer are the same. For example 2+2 and 3+1 are equivalent. They both equal four. In these problems are x=3 and x=3.5 they are the same beause of the answer on problem 2 6-x. That makes them both have the same answer
Step-by-step explanation:
7x-9=12
+9=+9
7x=21
/7=/7
x=3
The answer is 233
we solve the bracket first then multiplay then add
The bases of the prism are the triangular faces.
One side is marked 3 units. The vertical sides to the left of the triangles are 4 units. In a right triangle, if the legs measure 3 and 4, the hypotenuse measures 5.
The three sides of the triangular base measure 3, 4, and 5.
Perimeter = sum of the lengths of the sides
Perimeter = 3 + 4 + 5 = 12
Answer: 12 units
The correct answer (the one that isn't true) is the last one, "angle 1 and angle 2 are equal"
