Answer:
D
Step-by-step explanation:
Perimeter formula : P = 2l + 2w
l = 14
68 = 28 + 2w
2w = 40
w = 20
Area formula : l * w
14 * 20 = 280
Here, As the exponent and base both are different, we can't simply it by using any mathematical rule, so we have to convert them into decimal then comparing with options.
So, <span>5^3/4 + 2^11/12
= 3.34 - 1.88
= 1.46
Which is most precise to </span><span>2^7/12 </span><span>= 1.49
In short, Your Answer would be: Option D
Hope this helps!</span>
Isolate the variable by dividing each side by factors that don't contain the variable.The answer would be C. 1/5
Answer: Marianne would have to get a 79 on her final test.
Step-by-step explanation: In order to get the average, you have to add all of your numbers up and multiply by how many numbers you have (in your case, 3) and you will find your answer.
79+81+77=237 237 divided by 3 is 79. ( Sorry I used a calculator :( )
It should be 75 if you divide the area by the amount of sides. I don’t know if I’m right if I’m wrong I’m sorry!
