Answer:
152 ft. cubed
Step-by-step explanation:
Split the figure into two: 4x4x5 and 6x4x3
Solve:
4*4*5=80
6*4*3=72
80+72=152
What do you need help with?
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33
