Answer:

Step-by-step explanation:

for a triangle to be a right triangle, the sum of the square of its legs must equal the square of its hypotenuse

a² + b² = c²

in this problem, 4² + 10² ≠ 11²

16 + 100 ≠ 121

Georgia [21]

Answer:

$x+y\geq30$

$6c+7b\geq175$

Step-by-step explanation:

Given : Let c represents the number of boxes of chocolate chip cookies and b represents the boxes for butter cookies.

Anna is selling boxes of chocolate chip cookies (c) for $6 each and boxes of peanut butter cookies (b) for $7 each.

i.e. Cost of 'c' chocolate chip cookies = 6c

Cost of b butter cookies = 7b

She must sell at least 30 boxes of cookies and at least $175 worth of cookies.

i.e. $x+y\geq30$

$6c+7b\geq175$

Thus , the system of inequalities models this situation :

$x+y\geq30$

$6c+7b\geq175$
