The circular top of a concrete test cylinder has a 6-inch diameter. if the top of the cylinder is able to withstand 72,400 pounds of force, calculate the psi strength of the concrete (recall that psi refers to pounds per square inch). hint: you are only considering the weight and the area of the circle at the top of the cylinder. round your answer to the nearest whole number.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

c-   36

taxicab circle radius 9 has 4(9) = 36 points

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

1/4 is the answer if i recall correctly.
