Answer:
8.60
Step-by-step explanation:
A^2+B^2=C^2
5*5=25 7*7=49 49+25= 74
√ 74= 8.602...
Answer:
The answer is 960
Step-by-step explanation:all you would have to do is multiply the lenth times width. 40x24=960
Answer:
Can you please give a clearer explanation of what is your question?
Step-by-step explanation:
Answer: w=5 , L= 2+2(5)=12
Step-by-step explanation:
L=2+2W
A= 60
LxW=60, now we will replace the L
(2+2W)(W)=60 we multiply
2w^2+2w=60
2w^2+2w-60=0 we divide by 2 the equation so we can work easier
w^2+w-30=0
find out w using the quadratic equation
we will get 2 solution,
w=5 and another solution is -6, which is not valid, as the side can not be negative
