Answer:
We need to find the lowest common divisor which is the smallest possible number that is dividable by ALL numbers.
We have the following numbers:
For the denominators (3, 3, 5, 5) the least common multiple (LCM) is 15.
LCM(3, 3, 5, 5)
. Therefore, the least common denominator (LCD) is 15.
Rewriting the original inputs as equivalent fractions with the LCD:
125/15, 300/15, 75/15, 180/15
Answer:
C. 48°
Step-by-step explanation:
Maybe if multiply 80 by 3 so you can find one of the answer then do it algebraic
Answer:
3^2
Step-by-step explanation:
When multiplying, add the powers.
When dividing, minus the powers
3^3 * 3^3 / 3^4 = 3^(3 + 3 - 4) = 3^2
Answer:
b -17
Step-by-step explanation:
−a^2 − 3b^3 + c^2 + 2b^3 − c^2 =
= -(3²) - 3(2³) + (-3)² + 2(2³) - (-3)²
= -9 - 3(8) + 9 + 2(8) - 9
= -9 - 24 + 9 + 16 - 9
= -17
