You work in a hardware store. You have two boxes of nails. The first box weighs 6 pounds, 7 ounces, and the second box weighs 2 pounds, 9 ounces. Which equation can be used to calculate how much the two boxes weigh in
ounces?
ounces = 16(6 + 2) + 16
ounces = 16(6 + 2)
ounces = 16(6 * 2) +16
ounces = 16(6 x 2)
ounces = 16(6-2)

i'm not really sure how to answer that

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
