Since the 2 triangles are congruent (exactly the same), we know that side AD is the same as side AB. Since we know they are equal, you can write it as...
3y = 21
Divide both sides of the equation by 3 to solve for y, and you get y = 7.
The answer is A) 7*
Answer:
C) x = 1 / 2
Step-by-step explanation:
Formula for volume of a cube = a^3 ('a' to the power 3 or 'a' cubed)
a = side
Since volume = 1/8 ,
cube root of 1 / 8 will equal the side of the cube(which is 'x').
cube root of 1 / 8 = 1 / 2
answer = 1 / 2
Answer:
D.
Step-by-step explanation:
In order for it to be the solution, it must be less than or equal to -2. D (-1.76) is bigger than -2, which means it is not a part of the solution.
