Describe a real life multiplication situation for which an estimate make sense

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet
