The center will be halfway between the diameter so
x= (-3-7)/2 = -5
y= (-4-14)/2 = -9
therefore the center is at
(-5,-9)

The sum of the squares of two positive integers is 185. If one integer is 3 less than the other, fine the larger integer.

Answer:

$\boxed{\sf \ 11 \ }$

Step-by-step explanation:

Hi,

let's note the two integers a and b

$a^2+b^2=185 \ and \\\\a = b - 3$

We are asked to find b

replace a in the first equation

$(b-3)^2+b^2=185\\\\b^2-6b+9+b^2=185\\\\ 2b^2-6b+9-185=0\\\\ 2b^2-6b-176=0\\\\ b^2-3b-88=0\\\\b^2+8b-11b-88=0\\\\b(b+8)-11(b+8)=0\\\\(b-11)(b+8)=0\\\\ b = 11 \ or \ b = -8$

As b must be a positive integer, the solution is 11

Hope this helps

What number has the same value as 30 tens

Yuliya22 [10]

Multiplication should be used here. 30 tens means number ten should be added 30 times. 10+10+...+10 thirty times, which can be written as 10 x 30 which gives us the number 300. We get the same answer if the value of 10 thirties is required. We can use the same way to get the answer like the question given in the begging.
