Answer:
Which are equivalent expressions?
Check all that are true.
y + x = 2x
x + x + x + x = 4x (true)
x + x = 2x (true)
x + y + y + x = 2x + 2y (true)
x + y + x + x = 2x + y
Step-by-step explanation:
Answer:
4.58
Step-by-step explanation:
Using the formula
a^2=(c^2)-(b^2)
a^2=(5^2)-(2^2)
a^2=25-4
a^2=21
Using Square root on Both Sides
a=4.58
The right triangles are congruent, so
.. 2x -14 = 37 -x
.. 3x = 51 . . . . . . . add x+14
.. x = 17 . . . . . . . . divide by 3
x = 17
