STALIN [3.7K]

Answer:

7 meters by 5 meters, or vice versa

Step-by-step explanation:

p = 24 meters

a = 35 meters²

Formula for perimeter = l + l + w + w

Formula for area = l · w

7 and 5 are the only values where the rules are satisfied.

x + x + y + y = 24

7 + 7 + 5 + 5 = 24

14 + 10 = 24

x · y = 35

7 · 5 = 35

Find the least common denominator for these fractions. Enter your answer in
Tju [1.3M]

Answer:

LCD = 12

Equivalent Fractions with the LCD

5/6 = 10/12

5/4 = 15/12

Step-by-step explanation:

Rewriting input as fractions if necessary:

5/6, 5/4

For the denominators (6, 4) the least common multiple (LCM) is 12.

LCM(6, 4)

Therefore, the least common denominator (LCD) is 12.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

5/6 = 5/6 × 2/2 = 10/12

5/4 = 5/4 × 3/3 = 15/12

I used a least common denominator calculator so I hope this helped!!

Sphinxa [80]

Answer:

slope= -1/5  y intercept 3

Step-by-step explanation:

(0,4) and (-5,5) can be rewriten as 5-4/-5-0, which equals -1/5. Then, you plug the numbers into the equation y= mx+b to get -4=-1/5(5)+b. That gets 3.
