5x+30- 2x+9
3x+39 is the expression.
Answer:
The legs of a 45 45 90 triangle are congruent so if one leg is x we can write (using the Pythagorean Theorem):
x² + x² = 18²
2x² = 324
x² = 162
x = 9√2

Take the amount of points she has and subtract what she has
25-5
Answer:
5
Step-by-step explanation:
3+2x=5x
3=3x
x=1
PR=5
The answer is A, 1. In the statement x^2 >x, if we try 4, 5 and 8 for x, we get 16, 25 and 64 for x^2. The statement is true. But if we try x = 1, when we square it we still have 1. Therefore for x=1, x^2>x is false.
