Answer: 
Step-by-step explanation:
x^2+y^2=r^2 --> subtract x^2 to other side
y^2=r^2-x^2 --> square root both sides
y=sqrt(r^2-x^2)
Answer:
3x2+120x
Step-by-step explanation:
=(x+40)(3x)
=(x)(3x)+(40)(3x)
=3x2+120x
2 consecutive integers : x and x + 1
x + x + 1 = 183
2x + 1 = 183
2x = 183 - 1
2x = 182
x = 182/2
x = 91
x + 1 = 91 + 1 = 92
ur 2 numbers are 91 and 92 with 91 being the smallest integer
There is nothing wrong with Arlene's math. Her answer is correct. The mistake is that she has cited the "associative property" where the "commutative property" should have been cited, and vice versa.
The associative property has to do with where you put parentheses. The commutative property has to do with what order the operands are in.
