Answer:
The absolute value.
Step-by-step explanation:
X^2 + 3x + 2 = 0
(x + 1)(x + 2) = 0
x + 1 = 0 or x + 2 = 0
x = -1 or x = -2
x^2 + 2x + 1 = 0
(x + 1)(x + 1) = 0
x = -1
Xy(9x)(5x^3y) so the greatest common factor is xy
Answer:
Step-by-step explanation:
Example: Solve this triangle
right angled triangle 5 12 c
Start with: a2 + b2 = c2
Put in what we know: 52 + 122 = c2
Calculate squares: 25 + 144 = c2
25+144=169: 169 = c2
Swap sides: c2 = 169
Square root of both sides: c = √169
Calculate: c = 13
The correct answer is B. s+9
The keyword is more than, so you would add 9 to s. It's not D. because it is using the number 10 instead of 9.
Hope this helps!!
