Step-by-step explanation:
Answer:
14 yds
Step-by-step explanation:
To find the perimeter, we add up all the sides
P = s1 + s2+ s3 + s4
38 = 5.8+7+11.2 + s4
Combine like terms
38 = 24+s4
Subtract 24 from each side
38-24 = 24-24 +s4
14 = s4
The 4th side is 14 yds
Answer:
1. 10 miles
2. 12 feet
Step-by-step explanation:
For question 1, they both walk for two hours so Sara walked 8 hours and her sister walked 6 miles. Since they went 90˚ opposite directions, we have to use the Pythagorean Theorem to find the distance. 8 squared plus 6 squared equals c squared. 64 plus 36 equals c squared. The square root of 100 is 10, so the distance is 10 miles.
For question 2, you also have to do the Pythagorean Theorem. So, since the hypotenuse is 15, we do 15 squared minus 9 squared equals b squared. 225 minus 81 equals b squared. 144 equals b squared. The square root of 144 is 12. The answer is 12 feet. I hope this helped and please mark me brainliest. I spent I lot of time on this!
Answer:
The answer is 17/36
Step-by-step explanation:
First you multiply 1/4 times 9/9 and you get 9/36. Then you multiply 2/9 times 4/4 and you would get 8/36 and 8/36 + 9/36=17/36.
Answer:
g=3
Step-by-step explanation:
(x+7)(x-4)=x(x-4)+7(x-4)=x²-4x+7x-28=x²+3x-28
it should be gx ,then g=3
if ge then ge=3x
