The largest square that can fit in a square of radius 3cm can have its diagonal length twice its radius.
But diagonal of a square is root square root of {2} x length of each side.
Hence from above, diagonal length is 6 cm and so, the side can be 3*(2^1/2)
So area of square is (3*(2^1/2))^2 = 18 cm^2
Answer:
53
Step-by-step explanation:
when c=6 and d=5 we want to substitute the variables with the numbers in the equation so we'll have
(5) + 8(6)
after evaluating we come up with the answer 53
When we have mixed signs we need to make it a negative. A plus and a minus or a minus and a plus are made into a minus by default.
With that in mind the question would not turn into 1 - 2 =
From here we take the sign of the bigger number. The bigger number would be negative 2 and we put it as the first part of our solution
This next step might be easier with a number line from -5 to 5
We start at positive 1 on the number line. From here we need to go left because when subtracting you go left. We move two spaces to the left. So the one goes to 0 and then it goes to -1
The answer would turn out to be <u>negative one</u><u>(</u><u>-1</u><u>)</u>
<u>1</u><u> </u><u>-</u><u> </u><u>2</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>1</u>
HOPE THIS HELPED!!! PLEASE DONT FORGET TO PUT THIS ANSWER AS THE BRAINLIEST. ALSO, LEAVE A HEART AND A 5 STAR TO LET PEOPLE KNOW IN THE FUTURE THAT THIS IS THE CORRECT ANSWER WITH A CORRECT EXPLANATION!! HAVE A GOOD DAY!
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
Okay I did the work and I think it’s either answer a or b but goodluck sorry
But I still don’t understand this.
