Does anyone know this a. 5.831 mb. 16.552 mc. 2.828 md. 13.267 m

D. 13.267 m

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

7^2 + b^2 = 15^2

49 + b^2 = 225

Subtract 49 from each side

b^2 = 225-49

b^2 =176

Take the square root of each side

sqrt(b^2) = sqrt(176)

b = sqrt(176)

b = 13.266

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
