Area = 304 cm^2
perimeter = 70
perimeter = 2(l+w)
70 = 2(l+w)
70/2 = l+w
35 = l+w
Now suppose the length would be = x
width would be= 35-x
NOW Area = l*w
304 = x * (35-x)
304 = 35x -x^2
x^2-35x+304 = 0
use quadratic formula to solve next ok

8 feet is the longest side so it would be the hypotenuse. Use the Pythagorean formula to check.
a^2 + b^2 = c^2
3^2+5^2 = 8^2
9 + 25 = 64
34 = 64
This is obviously not true si it is not a right triangle.
Answer:
false
Step-by-step explanation:
860 divided by 2 is 430 NOT 480
Answer:
x = -15
Step-by-step explanation:
7 - 3x = -4(2+x)
7 - 3x = -8 -4x
7 + x = -8
x = -15
Answer:
Your answer is C
Step-by-step explanation:
0.5 = Five tenths
and
0.05 = five hundredths
This is because 0.5 is like 50 cents and 0.05 is like 5 cents
The rest are wrong because A: 0.05 simply can't be bigger than 0.5
B is wrong because they aren't equal to each other
and D is wrong because 0.05 + 0.5 = 0.55
