I’m sure that the area is 80. If you do 10 times 5, that will be 50.Then if you do 6 times 5, for the upper remaining part of the figure it would be 30. So 30 plus 50 is 50. Hope this helps!

what is the side length of a square given the area to be 625m

Answers

Answer: 25 meters

Step-by-step explanation:

✓625 = 25

Answer:25

Step-by-step explanation:A square has equal length on all its sides, so the area of square is

Length x Length = 625

Which is

Length ^2 = 625

We want the number that when it times it’s self it’s 625

It can be done by square root of 625 which is 25. So the length of side is 25.

Or look at the prime factorization of 625 ( or just factors) and what number they can make up

Which is 5x5x5x5 = 625

They can make up

5^2 x 5^2 = 25 x 25 that is the “same” number

So the length is 25

What is the sum of the 12th square number and the 10th square number?

Answers

Answer:

12^2 is 144 and 10^2 is 100 :)

Step-by-step explanation:

12 * 12 = 144

10 * 10 = 100

The sum of the 12th square number and the 10th square number is 244. This problem is based on the principle of addition.

The principle of addition states that when two numbers are added together, their sum is a unique number which is not necessarily be divisible by either the numbers or their factors. The addition is inverse operation of the subtraction.

The square of 12th number is 12² = 12 × 12 = 144.

The square of 10th number is 10² = 10 × 10 = 100.

The sum of both numbers = 144 + 100 = 244.

Hence, the answer to the given problem is 244.

You’re going to want to distribute the number directly before the parenthesis. So for number 1 you’re going to want to distribute the -11 to x+9 so the equation would look like: x-8=43-11x-99. Then combine like terms: x-8=-56-11x then add 11x to move the x’s to one side: 12x-8=-56 then add 8 to move it away so the x’s are alone. 12x=-48 then divide the -48 by 12 to get the x fully alone so you’d get x=-4
