Answer:
(a) see attached
(b) CD = 29
Step-by-step explanation:
<h3>(a) </h3>
See the attachment for a diagram.
In the diagram, we have shown point E on the plane so that BE is parallel to AC.

<h3>(b)</h3>
Triangle BDE is a right triangle with hypotenuse BD = 25 and leg BE = AC = 15. The length DE is given by the Pythagorean theorem as ...
DE = √(BD^2 -BE^2) = √(625 -225) = 20
Triangle CDE is a right triangle with hypotenuse CD and legs CE = 21 and DE = 20. The length of the hypotenuse is also given by the Pythagorean theorem as ...
CD = √(CE^2 +DE^2) = √(21^2 +20^2) = √841
CD = 29

Answer:
a² = b² -w² +2wx
Step-by-step explanation:
The algebra is pretty straightforward. Expand the expression in parentheses and add x².
b² -(w -x)² = e² = a² -x²
b² -(w² -2wx +x²) = a² -x² . . . . . expand the square
b² -w² +2wx -x² = a² -x² . . . . . . distribute the minus sign
b² -w² +2wx = a² . . . . . . . . . . . . add x²
If she uses 7.5 cups of flowers for 6 pies, then you need to find the "ratio". So first you need to divide 6 from 7.5, and that gets you 1.25. So that means that for one pie she uses 1.25 cups of flour!
