<span>The expression with an interval of [0,1] means all set of numbers including 0 and 1 and numbers within the range. In this case, the minimum sum could be 0 since x and y could be zero. The maximum is 2 since the two variables could be 1. The interval of x+y should be [0 , 2 ].</span>

It could be 0 and 0 which yeilds a value of 0
it could be 1 and 1 which yields a value of 2

any number from 0 to 2

Answer:

$\boxed{\sf \ \ \ x^2 + x -72 = 0 \ \ \ }$

Step-by-step explanation:

Hello,

We need to use the <u>distributive property</u> which means that for a, b and c real numbers a(b+c)=ab+ac

So here we can write

$x(x+1)=72\\ x*x+x*1=72\\ x^2 + x -72 = 0\\$

Solve for the missing side round to the nearest 10th (look at image)

Answer:

14.3

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

14^2 + 3^2 = c^2

196 + 9 = c^2

205 = c^2

Take the square root of each side

sqrt(205) = sqrt(c^2)

14.31782106 = c

Rounding to the nearest tenth

14.3 = c
