Lets find out..

(14 + 12) * (8 + 12) = 26 * 20 = 520
(14 * 12) + (8 * 12) = 168 + 96 = 264

nope, Larry is incorrect

The strength of a rectangular beam varies

aleksandrvk [35]

Answer:

1296 pounds per square inch

Step-by-step explanation:

<u>Direct variation equation:</u>

y = kx

<u>In this case it is:</u>

y = kx², where y- strength, x- depth of the beam, k- coefficient

<u>Substitute the given values and solve for k:</u>

3600 = k*10²
3600 = 100k
k = 3600/100
k = 36

<u>The equation becomes:</u>

y = 36x²

<u>Now, find the value of y, when x is 6:</u>

y = 36*6² = 1296

<u><em>Note, I took the depth as 6 inches but the question is a bit confusing by saying "four six inches". If it is 4 inches then your answer will be:</em></u>

y = 36*4² = 576
