Well we know that the formula for a diagonal is: d= \sqrt{2} a so using this we can conclude that the length and the width of this particular square would be 7.071 cm. Hope this helps!

Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26. What is the solution
Morgarella [4.7K]

Answer: ( -∞ , - 21 )

Step-by-step explanation:

Let the number be x , so from the question , we have

5(x+27) ≥ 6 ( x + 26 )

expanding , we have

5x + 135 ≥ 6x + 156

5x - 6x ≥ 156 - 135

- x ≥ 21

Therefore :

x ≤ - 21

So , the numbers less or equal to -21 are -21 ,-22 , -23 ...

so the solution set is ( - ∞ , 21 )

HELP! Please pyth. theorem
Alex

<u>Given</u>:

The given triangle QPO is a right triangle.

The length of QP is 5 units.

The length of OP is (x + 5) units.

The length of QO is (x + 6) units.

We need to determine the hypotenuse of the triangle QPO.

<u>Value of x:</u>

The value of x can be determined using the Pythagorean theorem.

Thus, we have;

QO^2=QP^2+OP^2

Substituting the values, we get;

(x+6)^2=5^2+(x+5)^2

Expanding, we get;

x^2+12x+36=25+x^2+10x+25

Adding the like terms, we get;

x^2+12x+36=x^2+10x+50

       12x+36=10x+50

         2x+36=50

                 2x=14

                   x=7

Thus, the value of x is 7.

<u>Length of the hypotenuse:</u>

The hypotenuse of the triangle QPO is QO.

Substituting x = 7 in the length of QO, we get;

QO=7+6

QO=13

Thus, the length of the hypotenuse is 13 units.

Hence, Option D is the correct answer.

Help? I'm not exactly sure how to do this :/
uranmaximum [27]
What you do is plug the z value (first column) into the formula (second column), and solve for y. For instance, the first one would be y = -1-2, or -3. The x would be the x in the ordered pair, and the final ordered pair would be (-1,-3). Make sense?
