Arectangle is 70ft longer then it is wide. each diagonal between opppsote corners is 130 ft. what are the dimensions?

w^2 + 70w + 2450 = 8450

w^2 + 70w - 6000 = 0

.

Factoring the left:

(w-50)(w+120) = 0

.

w = {-120, 50}

.

toss out the negative solution:

width is 50 feet

length is 50+70= 120 feet

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
