Step-by-step explanation:
FOR example 2x2 equal 4and I don't know this sorry
Solve the given equation:
13 + x = 29
Subtract 13 from both sides:
x = 16
Now look at each choice and solve for x.
A. 29 + 13 = x
x = 42
B. 13 = 29 - x
-16 = -x
x = 16
C. x = 29 - 13
x = 16
D. 13 - x = 29
-x = 16
x = -16
Choices B and C have the same solution as the given equation, so choices B and C are equivalent to the given equation.
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side of the triangle is sqrt(10) too. By using Pythagoras theorem, we have 10+10=x^2, x=2*sqrt(5).
