et H be the set of all vectors of the form [Start 3 By 1 Matrix 1st Row 1st Column 4 t 2nd Row 1st Column 5 t 3rd Row 1st Column 9 t EndMatrix ]. Find a vector v in set of real numbers R cubed such that Upper H equals Span StartSet Bold v EndSet. Why does this show that H is a subspace of set of real numbers R cubed?

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

the answer is  

a.

4,624π mm2
